Fort Irwin National Training Center
from Wikipedia

Fort Irwin National Training Center (Fort Irwin NTC) is a major training area for the United States military in the Mojave Desert in northern San Bernardino County, California. Fort Irwin is at an average elevation of 2,454 feet (748 m).[1] It is located 37 miles (60 km) northeast of Barstow, in the Calico Mountains.

Key Information

The National Training Center is part of the US Army Combined Arms Command (CAC). The opposing force at the National Training Center is the 11th Armored Cavalry Regiment, the Blackhorse Cavalry, who are stationed at the base to provide an opposing force to units on a training rotation at Fort Irwin. In September 2017, a state-of-the-art hospital was opened that provides healthcare services to the Fort Irwin beneficiaries.

Fort Irwin works within the R-2502 Special Use Airspace Complex.

History

[edit]

The Fort Irwin area has a history dating back almost 15,000 years, when Native Americans of the Lake Mojave Period were believed to have lived in the area. Native American settlements and pioneer explorations in the area were first recorded when the Spanish missionary Padre Francisco Garces traveled the Mohave Trail with Mohave Indian guides in 1776. During his travels, he noted several small bands of Indians, and is believed to have been the first European to make contact with the Native Americans of the area.

Jedediah Smith is thought to have been the first European American to explore the area in 1826. A fur trapper, Smith was soon followed by other pioneers traveling the Old Spanish Trail between Santa Fe and Los Angeles. The trail crossed the area on the eastern edge of Fort Irwin, between Salt Spring and the Mojave River. The Old Spanish Trail passed through Silurian Valley, then west through the Avawatz Mountains at Red Pass and beyond the playa of Red Pass Lake, through a gap between the Soda and Tiefort Mountains to Bitter Spring in a wash in the next valley. Bitter Spring was the only reliable watering and grazing place along the route. From Bitter Spring the trail led 18.75 miles (30.18 km) southwest climbing Alvord Mountain to cross Impassable Pass to descend Spanish Canyon and cross the plains to the location of Fork of the Road on the north side of the Mojave River where it met the Mohave Trail.

In 1844, Captain John C. Fremont, accompanied by Kit Carson, was the first member of the US Army to visit the Fort Irwin area. Captain Fremont established a camp near Bitter Springs as he pioneered a route that served travelers on the Old Spanish Trail, and later the Mormon Road, linking Salt Lake City to California. This camp was later to become an important water and grazing place for pioneers crossing the Mojave Desert during California's settlement and gold rush.

The California Gold Rush brought prosperous trade and unexpected trouble to the area. As California grew, and more travelers and freighters used the Mormon Road to cross the territory between California and Utah, raids and horse stealing became a problem. In 1847, the Army's Mormon Battalion patrolled the Fort Irwin area to control the raiding and horse stealing. By 1855 it became part of the route of the freight wagon road between Los Angeles and Salt Lake City.[2]: 13, 15  During the Bitter Spring Expedition in 1860 the Army constructed Camp Bitter Springs, a small stone fort overlooking Bitter Spring and patrolled the Fort Irwin area.[3]

In the 1880s the area experienced an economic boom with the discovery of borax at Death Valley. From the late 19th century to the early 20th century, the area began to grow tremendously as mining operations of all types flourished. Soon railroads, workers, and businesses led to the establishment of the nearby town of Barstow.

The years following the Indian Wars were quiet militarily. In 1940, President Franklin D. Roosevelt established the Mojave Anti-Aircraft Range, a military reservation of approximately 1,000 square miles (3,000 km2) in the area of the present Fort Irwin. In 1942, the Mojave Anti-Aircraft Range was renamed Camp Irwin, in honor of Major General George LeRoy Irwin, commander of the 57th Field Artillery Brigade during World War I, and it was subsumed into the Desert Training Center as one of its cantonment areas and some of its ranges. Two years later, Camp Irwin was deactivated and placed on surplus status.

Camp Irwin reopened its gates in 1951 as the Armored Combat Training Area and served as a training center for combat units during the Korean War. Regimental tank companies of the U.S. 43d Infantry Division from Camp Pickett, Virginia were the first to train at the new facility.

The garrison was designated a permanent installation on 1 August 1961 and renamed Fort Irwin. During the Vietnam buildup, many units, primarily artillery and engineer, trained and deployed from Fort Irwin.

In January 1971, the garrison was deactivated again and placed in maintenance status under the control of Fort MacArthur (Los Angeles), California. The California National Guard assumed responsibility for the garrison and from 1972 to 1980, Fort Irwin was used primarily as a training area by Army National Guard and U.S. Army Reserve units.

National Training Center

On 9 August 1979, the Department of the Army announced that Fort Irwin had been selected as National Training Center (NTC). The location – an isolated area – was ideal because of its over 1,000 square miles (2,600 km2) capacity for maneuver and ranges, its uncluttered electromagnetic spectrum, and its restricted airspace. The National Training Center was officially activated 16 October 1980, and Fort Irwin was transferred from the California Army National Guard back to the Regular Army returning into active status on 1 July 1981.

The NTC was unique in its training approach in the use of Real Time Location System (originally a General Dynamics microwave transponder system; later replaced by GPS); the use of lasers to simulate direct fire (including small arms); and the use of real time interactive computer models for indirect fire along with Air to Ground and Ground to Air missile systems. Originally developed as a prototype by the US Army's Fort Hunter-Liggett with Systems and Software design the BDM, the NTC system was the first to augment After Action Reviews of training exercises with video and maneuver overlays including time stamped combat events.

Since its activation, the NTC has witnessed many other firsts. Among the first units to train against the Opposing Force (OPFOR) were 1st Battalion, 22nd Infantry and 1st Battalion 77th Armor, 4th Infantry Division (Mech) from Fort Carson, Colorado in Spring 1978 as a proof of concept FX for establishing Irwin as the NTC, the 3rd Battalion 67th Armor, 2nd Armored Division from Fort Hood, Texas in operation TASK FORCE IRWIN III, 1 Aug – 14 Sept, 1979, and 3rd Brigade, 1st Cavalry Division from Fort Hood, Texas in spring 1981. Also Ft Irwin and the 1st CAV tested and implemented the Multiple Integrated Laser Engagement System (MILES). Infantry and armor units first augmented the Opposing Force in 1984 as a detachment of the 7th infantry Division, Fort Ord CA. June 1985 saw the first use of M1 Abrams tanks and later in the fall of 1985 saw the M2 Bradley fighting vehicles on the NTC battlefield. The first armored cav. squadron rotation occurred in November 1984. Units from the 101st Airborne Division participated in the first light force rotation in March 1985. The 197th Infantry Brigade participated in the first extended rotation with brigade operations in June 1985. The first combined Light/Mechanized Infantry rotation took place in February 1990; the 7th Infantry Division (Light) from Fort Ord and the 24th Infantry Division (Mechanized) from Fort Stewart, Georgia participated. The first MOUT (Military Operations in Urban Terrain) mission was conducted at the NTC Pioneer Training Facility in December 1993.

Opposing Forces (OPFOR)

[edit]

During the re-opening of the NTC in 1980, the OPFOR consisted of re-activation of the 6th Battalion, 31st Infantry, "The Polar Bears," from the 7th Infantry Division, based in Fort Ord, California, and the 1st Battalion, 73rd Armor. Once the US Army turned to regimental units in 1985, the OPFOR was redesignated the 177th Armored Brigade (SEP). The OPFOR soldiers were dressed in Soviet-style armor uniforms including black berets, Soviet-style insignias, and used M551 Sheridans visually modified to resemble BMP-1 vehicles and T-72 tanks. In their OPFOR role the Infantry Battalion was designated as the 32nd Guards Motorized Rifle Regiment. U.S. Marine Corps (USMC), U.S. Army Reserve and Army National Guard units would support infantry roles for the OPFOR.

Air support and air combat tactics came from USAF fighter wings operating from Nellis AFB and George AFB. USN strike squadrons from NAS Lemoore, USMC fighter/attack squadrons operating from MCAS El Toro, and USMC helicopter attack squadrons operating from MCAS Tustin. When George AFB, MCAS El Toro and MCAS Tustin were closed as a result of Base Realignment and Closure Commission actions in the 1990s, USAF air support shifted to composite fighter wings from Nellis AFB, Hill AFB, Luke AFB and Davis-Monthan AFB. USMC air support shifted to MCAS Miramar (formerly NAS Miramar), MCAS Yuma and MCAS Camp Pendleton.

During the 1980s and 1990s, the NTC also showcased US Army large-scale tactics to foreign military leaders from all over the world. The OPFOR ran 15 training rotations a year against armored brigades from both Active and Reserve Component US Army units from all over the United States. The command centers of these large-scale battles were computerized in a central command post, where each battle was recorded and analyzed. The results were subsequently debriefed to the participants.

After the September 11, 2001 attacks, the NTC transformed to focus on continuous counterinsurgency ops that reflected a rapidly changing battlefield, especially in desert climate environments.

Following the United States withdraw from Afghanistan in 2021 and the Russian invasion of Ukraine in early 2022, The National Training Center began to train soldiers for future fights against major near-peer adversaries.[4]

Description

[edit]

The Post is composed of the Fort Irwin garrison with general support facilities such as:

  • Post Emergency Services
  • Public Affairs Service
  • Veterinary Service
  • Housing, Financial, Admin and Community Services
  • Religious Support and Social Services
  • Human Resources and Civilian Personnel Services
  • Environmental and Safety Office
  • Public Works

The National Training Center element of the Post which consists of the following units:

  • 11th Armored Cavalry Regiment (Blackhorse) acting as the 'enemy' for all training visiting units.
  • 916th Support Brigade providing support to the installation, and sustainment for visiting units and their operations.
  • The National Training Center (NTC) Operations Group which is responsible for all live training events.
  • The Joint Center of Excellence is facilitating individual, collective and unit counter IED training; evaluating existing and developing new operational techniques, tactical procedures and counter IED equipment concepts.
  • The Mission and Installation Contracting Command is responsible for the maintenance and logistics of all NTC and garrison facilities.
  • The Reserve Component Operations Plans and Training (RCOPT) facilitates integration of all reserve component formations at the NTC. It also serves as the NTC Command Group's advisor on all reserve component matters and educates all reserve units.

The NTC at Fort Irwin continues to serve as one of the US Army's main training centers. All US military services, as well as other government agencies and some foreign military units train at the NTC. A common tradition for any visiting military unit is to paint their sign on one of the rock formations near the main gate. Units of all types and locations are represented.

NTC training is not easy. The exercises incorporate complex scenarios exposing the units to detailed hybrid threats. Facing a strong opposing force and an insurgent force, at the same time, they must assist local people in towns and villages in the area in any way possible.

One of the NTC features is the presence of 12 mock-up "villages" used to train troops in Military Operations in Urban Terrain (MOUT) prior to their deployment. Collectively known as the fictional country of Atropia, these villages have religious sites, hotels, traffic circles, etc. filled with foreign 'locals'. These are Arabic speaking roleplaying actors portraying government officials, local militia, police, military, villagers, street vendors and insurgents. They will confront the military with all kinds of all-day problems.

The largest two villages are known as Razish and Ujen, the closest located about 30 minutes from the main part of the post. The largest village consists of 585 buildings that can engage an entire brigade combat team into a fight. The training uses simulated as well as live Unmanned Aircraft Systems (UAS), the Multiple Integrated Laser Engagement System (MILES) and incorporates multi-national forces and (social) media actions.

Observer, Controller and Trainers (OCTs) are embedded with the training units from brigade down to platoon level. Some villages are completely instrumented, including video recording, to assist the OC/T teams in providing feedback to the training unit.

Fort Irwin National Training Center is a installation situated in the of , approximately 35 miles northeast of Barstow, encompassing over 1,000 square miles of rugged terrain ideal for simulating diverse combat environments. Established as the National Training Center in 1981 to revolutionize training following doctrinal reforms in the late 1970s, it serves as the Army's premier venue for rotational units to conduct realistic, large-scale joint and exercises prior to deployments, training more than 50,000 soldiers annually through scenarios that emphasize tactical proficiency and operational readiness. The NTC's defining feature is its (OPFOR), embodied by the , which employs Soviet-style tactics and equipment replicas to challenge rotating brigades in force-on-force maneuvers across vast, instrumented ranges that incorporate live-fire, electronic warfare, and urban combat simulations unmatched elsewhere in the continental . This high-stakes training regime, developed from 1976 conceptual studies, has proven instrumental in enhancing and , with capabilities extended to division-level rotations and multinational partners amid evolving threats. Fort Irwin's isolation and scale—comparable to —enable unencumbered operations, including over 1,200 buildings and mock urban sites, while sustaining in its arid ecosystem.

History

Pre-NTC Establishment and Early Use

On August 8, 1940, President issued an withdrawing approximately 1,000 square miles of in the of from public use to establish the Mojave Anti-Aircraft Range (MAAR), a training area for anti-aircraft units preparing for potential in arid environments. This site, located about 35 miles northeast of Barstow in San Bernardino County, was selected for its vast, rugged terrain simulating conditions, with extreme temperatures often exceeding 120°F (49°C) in summer. In July 1942, amid escalation, the facility was redesignated Camp Irwin and expanded into a key component of General George S. Patton's Desert Training Center (DTC), a massive maneuver area spanning over 18,000 square miles across and to acclimate troops to desert combat. Camp Irwin served as a primary base for armored and units, hosting exercises that emphasized long-range maneuvers, live-fire , and survival in harsh conditions; over 1 million soldiers trained across the DTC network, with Camp Irwin supporting anti-aircraft, , and provisional groups through simulated battles against mock enemy positions. The U.S. Army Corps of Engineers' Los Angeles District collaborated with Patton's forces to construct temporary camps, roads, and firing ranges, enabling realistic training that contributed to Allied successes in by honing tactics for dust-choked advances and water-scarce logistics. Following the war's end in 1945, Camp Irwin was deactivated in 1944 amid reduced training needs, entering surplus status with minimal maintenance until reactivation on February 12, 1951, as the U.S. Army's Armor and Desert Training Center to address emerging requirements for mechanized forces in arid theaters. During the and 1960s, it hosted rotational training for battalions and armored cavalry regiments, focusing on gunnery qualification, live-fire maneuvers, and desert mobility exercises; units like the utilized the site's expansive ranges for brigade-level operations, though activity remained intermittent due to budget constraints and shifting priorities toward Vietnam-era . On August 1, 1961, after two decades as a temporary installation, Camp Irwin was redesignated a permanent U.S. post and renamed Fort Irwin, reflecting investments in such as , storage, and expanded firing ranges to support ongoing armor testing and evaluation. Through the , Fort Irwin operated on a reduced scale, primarily for and anti-armor testing by the 's Command, with caretaker units maintaining facilities amid debates over its future viability; environmental and land-use concerns from adjacent civilian areas occasionally limited expansions, but the site's isolation and terrain preserved its role as a specialized until preparations for the National Training Center began in 1979.

Creation and Early Operations of the National Training Center (1981–1990)

The National Training Center (NTC) at Fort Irwin was established to address critical deficiencies in U.S. training identified after the , emphasizing realistic, high-intensity maneuvers against a peer adversary simulating forces. Conceived in 1976 amid reforms under the Army's "Training Revolution," the NTC aimed to prepare armored and mechanized brigades for initial battles in potential European theater conflicts by providing instrumented, force-on-force exercises over expansive desert terrain. The Deputy Secretary of Defense approved its creation at Fort Irwin, , leading to official activation of the NTC on October 16, 1980, followed by Fort Irwin's return to active status on July 1, 1981. This reactivation repurposed the former site, previously used intermittently for training since , into a dedicated facility for brigade-level combat simulations. Early operations commenced with pilot rotations in 1981, focusing on armored maneuver battalions to test and refine training protocols. The 197th Infantry Brigade (Separate) conducted the initial training exercise in August 1981, followed by the first full maneuver battalion rotations in October 1981. These exercises employed Multiple Integrated Laser Engagement System (MILES) simulators for weapon effects, vehicle-mounted instrumentation for real-time tracking, and post-rotation after-action reviews (AARs) using data telemetry and video replays to dissect tactical decisions. Rotations typically involved 4,000 to 5,000 soldiers per brigade, executing multi-day scenarios in the Mojave Desert's rugged terrain, which, while not replicating European forests, facilitated large-scale armored operations under conditions of dust, visibility challenges, and extended logistics. Initial instrumentation systems faced technical startup issues, but by 1982, the first complete brigade rotation validated the model's efficacy in exposing doctrinal gaps and enhancing unit cohesion. The Opposing Force (OPFOR), initially drawn from ad hoc detachments, evolved into a dedicated unit emulating Soviet motorized rifle tactics with T-72 surrogates, BMP infantry fighting vehicles, and massed artillery simulations. Infantry and armor elements from the 7th Infantry Division augmented OPFOR starting in 1984, enabling more authentic threat replication. By the mid-1980s, monthly rotations had trained over 50 battalions in three years of full operations, yielding measurable improvements: units achieved higher simulated kill ratios, better fire discipline, and reduced fratricide through iterative AAR feedback. The first armored cavalry squadron rotation occurred in November 1984, expanding scope to reconnaissance-heavy forces. Through 1990, NTC operations prioritized heavy brigade combat teams under AirLand Battle doctrine, conducting approximately 10-12 rotations annually and transforming Army readiness by institutionalizing data-driven training over scripted exercises.

Post-Cold War Adaptations and Expansions (1991–Present)

Following the in 1991, the U.S. Army shifted focus from large-scale against peer adversaries to regional contingencies and operations, prompting adaptations at the National Training Center (NTC) to incorporate smaller-unit maneuvers and stability tasks alongside traditional combined-arms exercises. Training rotations continued to emphasize realistic force-on-force engagements, but scenarios began integrating elements of operations other than war, such as those observed in and the , while maintaining the core instrumentation system for after-action reviews that had proven effective in building unit cohesion. Land expansion efforts, initiated in the late 1980s, encountered significant delays post-1991 due to environmental regulations protecting the ; a 1991 U.S. Fish and Wildlife Service biological opinion restricted training areas, limiting maneuver space to approximately 1,000 square miles. By 2001, congressional directives led to a proposed expansion plan adding over 600 square miles across Eastgate, the Southern Expansion Area, and Superior Valley, finalized through species translocation agreements by 2005 to mitigate habitat impacts while enabling larger-scale rotations. The , serving as the (OPFOR), reflagged in 1994 to refine its role in simulating adaptive adversaries, evolving from strict Soviet-style tactics to hybrid threats incorporating guerrilla elements by the mid-1990s. In response to the , 2001, attacks and subsequent operations in and , NTC reoriented training toward and , constructing multiple mock villages for military operations in urban terrain (MOUT) to replicate insurgent-held settlements in desert environments. A $12 million urban training complex, opened in December 2007, featured 41 primary structures including a government center, , and guard towers, alongside 24 ancillary buildings to support platoon- and company-level stability operations. Garrison infrastructure expanded post-2001 to accommodate surging rotation demands, with improvements to housing and support facilities sustaining up to 10 annual brigade cycles amid Global War on Terrorism deployments. By the 2010s, NTC integrated asymmetrical warfare elements such as improvised explosive device lanes and intelligence-driven scenarios, preparing units for both counterinsurgency and decisive action against near-peer forces. Recent modernizations, including echelon-above-brigade support from a simulated 52nd Infantry Division and counter-unmanned aerial system training, reflect doctrinal shifts toward multi-domain operations as of 2024.

Mission and Training Operations

Core Training Methodology and Rotations

The National Training Center (NTC) at Fort Irwin conducts approximately ten brigade-level rotations annually, each designed to train rotational training units (RTUs), typically brigade combat teams, in large-scale combat operations through immersive, high-tempo exercises. Rotations involve deploying several thousand soldiers and equipment for a total period of up to 28 days, encompassing reception, staging, on-site training, the core (FTX), and redeployment, though the FTX itself focuses on 14 to 18 days of continuous operations. This structure prioritizes armored, , and infantry brigade combat teams, with occasional division-level rotations to test higher-echelon . Core training methodology centers on force-on-force simulations against a dedicated , utilizing the (MILES) to replicate direct-fire engagements without live , enabling safe, repeatable scenarios that assess tactical decision-making and . For instance, during NTC Rotation 19-04 in February 2019, the Japan Ground Self-Defense Force's 72nd Tank Regiment employed MILES on tanks and vehicles for simulating combat engagements in joint force-on-force training alongside U.S. Army Stryker units and the opposing force, illustrating multinational participation in NTC's training framework. Advanced instrumentation systems track vehicle positions via GPS, record simulated fires, and compute battle damage assessments in near real-time, feeding data into rigorous after-action reviews (AARs) that dissect performance at through levels. Separate live-fire exercises complement simulations, emphasizing integration, maneuver under contact, and sustainment in austere conditions to mirror peer-level threats. Rotations emphasize operational realism through phased progression: initial home-station preparation verifies prerequisites like crew qualifications, followed by NTC in-processing for instrumentation initialization, then escalating FTX missions involving defensive withdrawals, attacks, and urban operations across the center's expansive terrain. Units experience , logistical constraints, and electronic warfare effects to build resilience, with AARs driving iterative improvements across multiple iterations per rotation.

Effectiveness, Impact, and Criticisms

Achievements in Unit Readiness and Doctrine Development

The National Training Center (NTC) at Fort Irwin revolutionized unit readiness by implementing instrumented force-on-force in January 1982, using the (MILES) to simulate realistic combat losses and outcomes against a professional (OPFOR) modeled on Soviet motorized rifle tactics. This addressed longstanding training shortfalls identified in the , where units routinely underperformed in evaluations due to scripted, low-fidelity exercises; NTC rotations imposed high operational tempo over vast desert terrain, forcing adaptations in maneuver, logistics sustainment, and leader decision-making under stress, resulting in quantifiable gains in and tactical execution. By 1984, NTC was deemed a resounding success, with rotational brigades demonstrating doubled or tripled in kill ratios and mission accomplishment compared to pre-NTC benchmarks. NTC's structured after-action reviews (AARs), data analytics from thousands of engagements, and observer-controller insights have directly shaped Army doctrine, providing empirical feedback loops to the Training and Doctrine Command (TRADOC) for refining concepts like in FM 100-5 (1982 and 1986 editions). These processes identified causal gaps in , integration, and sustainment, leading to doctrinal emphases on initiative at lower echelons and deep maneuver, while influencing equipment upgrades such as improved and armored vehicle survivability. Rotational of 4,000–5,000 soldiers monthly has sustained these developments, with NTC serving as a for multi-domain operations prototypes, including joint fires and cyber integration in recent iterations. The impact extended to operational validation during the 1991 , where NTC-trained units achieved decisive overmatch, with coalition forces reporting incidents below 1% in ground operations—far lower than historical norms—and enabling rapid armored advances through application of NTC-honed tactics against Iraqi forces. This empirical success validated NTC's causal role in bridging training realism to battlefield dominance, prompting expansions in similar centers and ongoing adaptations for peer threats.

Criticisms Regarding Terrain Relevance, Costs, and Living Conditions

Critics have argued that the terrain at Fort Irwin National Training Center fails to replicate environments likely in conflicts with peer adversaries, such as the forested bogs of the , mountainous farms of Korea, or rice paddies and beaches of . This mismatch risks ingraining counterproductive tactics, including frequent command post displacements effective in open deserts but vulnerable to drone in concealed, high-tech battlespaces akin to those observed in . For instance, vehicle mobility, ambushes, engagement ranges, and fortification differ markedly between arid expanses and vegetated or urban terrains, potentially undermining unit preparation for multi-domain operations against near-peer threats. Operational costs at the National Training Center remain substantial, with individual brigade rotations estimated at up to $25 million each as of , amid approximately 10 rotations annually. Historical investments exceeded initial projections by over $125 million by the early , reflecting ongoing and sustainment demands in a remote location. These expenses encompass fuel, maintenance, and instrumentation for live-fire and simulated engagements across 1,000 square miles, though recent data on per-rotation figures post-2020 remains limited in public sources. Living conditions for soldiers at Fort Irwin have drawn complaints due to substandard , exacerbated by the base's isolation in the . Army-wide assessments, including a 2023 Government Accountability Office report, identified pervasive issues like mold, broken appliances, exposed sewage, and inoperable fire systems in , which degrade and readiness; Fort Irwin-specific upgrades, such as privatized junior enlisted initiated in 2025 with amenities like pools, were prompted by similar soldier-reported deficiencies. The harsh environment—extreme temperatures fluctuating from below freezing to over 100°F, pervasive dust leading to respiratory issues, and a 30-40 minute commute to off-base amenities—compounds isolation, with cost-of-living indices 16% above national averages, including elevated gas and grocery prices. Recent renovations aim to address morale impacts, but persistent remoteness and training demands continue to challenge welfare.

Debates on Future Adaptations for Peer Competitor Threats

Following the U.S. withdrawal from in August 2021, the reoriented training at the National Training Center (NTC) toward large-scale operations (LSCO) against near-peer adversaries like and , incorporating real-time lessons from the Russia-Ukraine war that began in February 2022. This shift emphasizes hybrid threats, including drone swarms for surveillance and strikes, massed artillery barrages, and electronic warfare jamming, with NTC rotations simulating "Denovian" forces mimicking Russian tactics such as infrastructure destruction and dissemination. To enhance realism, NTC's (OPFOR) units received upgraded combat vehicles starting in 2021, replacing aging M113-based surrogates with tracked and wheeled platforms designed to replicate modern Russian / or Chinese equivalents, complete with night-vision and thermal optics for brigade-level engagements. Rotations like Decisive Action 25-07, conducted in 2025, integrate these elements into multi-phase LSCO scenarios, aiming to prepare units for contested environments with over-the-horizon command posts and adaptive tactics against escalating threats. Debates persist over NTC's capacity to fully prepare forces for peer conflicts, particularly given the Mojave Desert's open terrain, which contrasts sharply with likely theaters like the forested bogs of the , mountainous Korean peninsula, or Taiwan's rice paddies and beaches. A 2025 analysis by the (AUSA) argues that this mismatch fosters suboptimal tactics, such as excessive command post mobility suited to deserts but vulnerable in vegetated areas where concealment—demonstrated in —enables survival against drones and . Critics, including AUSA essays, contend that NTC's brigade-scale exercises rarely scale to historical division- or corps-level maneuvers required for peer fights, potentially undermining readiness despite instrumentation enhancements. Proponents of NTC's model highlight its for data-driven after-action reviews and cost efficiencies, but detractors advocate supplemental on allied terrains abroad or U.S. sites like for urban and varied geography, warning that over-reliance on simulated adaptations risks doctrinal gaps against adversaries' integrated fires and long-range precision strikes. Existing OPFOR vehicle modernizations face implementation hurdles, including safety concerns from outdated platforms and bureaucratic delays in prototyping, fueling calls for accelerated investment to match evolving threats. As of 2023, amid heightened U.S.- tensions, NTC explicitly simulated Russian peer scenarios, yet analysts question whether these suffice without broader terrain diversification.
