The California National Guard (Cal Guard) is part of the National Guard of the United States, a dual federal–state military reserve force in the state of California. It has three components: the California Army National Guard, California Air National Guard, and California State Guard. As of 2025, the California National Guard comprises approximately 24,000 personnel, making it one of the largest National Guard forces in the United States.[1]
Since 2001, members of the California National Guard have been deployed overseas more than 38,000 times. Thirty-one California Guardsmen have died while serving overseas in support of operations in Iraq, Afghanistan, Kuwait, and Guantanamo Bay.[2][3]
The Constitution of the United States specifically charges the National Guard with dual federal and state missions. When under the control of its state governor, National Guard functions range from limited actions during non-emergency situations to full scale law enforcement of martial law when local law enforcement officials can no longer maintain civil control. The National Guard may be called into federal service in response to a call by the president or Congress.
When National Guard troops are called to federal service, the president serves as Commander-In-Chief. The federal mission assigned to the National Guard is: "To provide properly trained and equipped units for prompt mobilization for war, national emergency or as otherwise needed."


The governor of California may call individuals or units of the California National Guard into state service during emergencies or special situations. The state mission of the National Guard is: "To provide trained and disciplined forces for domestic emergencies or as otherwise provided by state law."
2025 federal deployment and legal challenge
[edit]In June 2025, the California National Guard became the subject of a high-profile legal and political dispute when President Donald Trump issued a memorandum federalizing up to 4,000 Guard members and deploying approximately 700 U.S. Marines to Los Angeles during protests following federal immigration raids.[4][5] Governor Gavin Newsom strongly opposed the move, asserting that it exceeded presidential authority under Title 10 and was unnecessary given local law enforcement's control.[6]
On June 9, the State of California filed suit in the Northern District of California, Newsom v. Trump, seeking to block the deployment via a temporary restraining order. The lawsuit contends the executive order violated 10 U.S.C. § 252, the Tenth Amendment, and the Posse Comitatus Act.[7][8]
On June 12, 2025, Judge Charles Breyer of the Federal District Court in San Francisco issued a 36-page ruling, returning control of the National Guardsmen back to Newsom. The second paragraph of the ruling reads:
At this early stage of the proceedings, the Court must determine whether the President followed the congressionally mandated procedure for his actions. He did not. His actions were illegal—both exceeding the scope of his statutory authority and violating the Tenth Amendment to the United States Constitution. He must therefore return control of the California National Guard to the Governor of the State of California forthwith.[9]

Military academy
[edit]The California National Guard maintains the California Military Academy at Camp San Luis Obispo, which houses the state's Officer Candidate School (OCS) program. This academy trains qualified enlisted personnel, warrant officers, and civilians to become commissioned officers in the California Army National Guard.
Upon completion of Basic Combat Training (BCT), OCS cadets attend monthly drills for approximately 16 to 18 months, followed by a two-week annual training. Graduates are commissioned as Second Lieutenants in the Army National Guard.[11] [12]
Accidents and incidents
[edit]In 1995, Shawn Nelson a former US Army officer entered a California National Guard armory undetected. He was able to start one of the tanks and he drove it around the streets of San Diego. After the incident, the San Diego mayor wrote a letter to the Californian Mayor demanding an investigation into armory security.[13]

Founding and Early Development (1849–1900)
The origins of the California militia trace to the state's constitutional convention held in Monterey from September 1 to October 10, 1849, where delegates adopted a constitution authorizing a state militia with the governor serving as commander-in-chief, empowered to call it forth to execute laws, suppress insurrections, and repel invasions.[9][10] This framework built on prior ad hoc volunteer forces, including the California Battalion formed during the 1846 Bear Flag Revolt and subsequent Mexican-American War operations under John C. Frémont, which had mustered about 400 soldiers across eight companies by 1847 before disbanding.[10] The first organized unit under the new constitution, the First California Guard—formally Company A, 1st Regiment of Light Artillery—emerged from San Francisco volunteers on July 27, 1849, to address immediate security needs amid the Gold Rush influx. California's admission as the 31st state on September 9, 1850, prompted rapid legislative action to operationalize the militia. On April 4, 1850, the inaugural legislature in San Jose passed enabling laws establishing a system of volunteer and independent companies, authorizing over 100 such units by year's end to maintain order during the chaotic Gold Rush era, when population surged from roughly 15,000 non-Native residents in 1848 to over 90,000 by 1850.[10] These forces, often underfunded and reliant on local initiative, focused on suppressing banditry, enforcing mining claims, and conducting expeditions against Native American groups resisting encroachment, as seen in the Mariposa Battalion's campaigns during the Mariposa Indian War (1850–1851), which involved several companies combating Miwok and Yokuts tribes.[10] By 1851–1861, dozens of county-based volunteer companies had formed, including infantry, rifle, and artillery units in San Francisco, Sacramento, and mining districts, though chronic shortages of state funding limited drills and equipment, rendering much of the militia a "paper army" effective mainly for short-term mobilizations.[10] Through the Civil War period (1861–1865), California's militia units, loyal to the Union, guarded coastal forts, suppressed Confederate sympathizers, and patrolled against potential raids, with no regiments deploying eastward due to the state's remoteness and federal regular army presence.[10] Postwar reorganization accelerated in 1866, when the legislature enacted Chapter DXLI of the Statutes, formally designating organized uniformed troops as the "National Guard of California" to standardize training and enable potential federal integration during emergencies, marking a shift from purely local volunteers toward a more structured force.[10] By the 1880s–1890s, the Guard expanded with improved armories and annual encampments, preparing for roles in labor unrest and natural disasters, though it remained volunteer-based and state-funded until the Spanish–American War mobilization in 1898, when over 1,000 Guardsmen formed the 7th Infantry Regiment for federal service in the Philippines.[10] This era solidified the Guard's dual state-federal character, with enrollment fluctuating between 2,000 and 5,000 amid economic booms and legislative reforms emphasizing discipline over ad hoc responses.[10]World Wars and Major Conflicts (1900–1945)
In response to Pancho Villa's raid on Columbus, New Mexico, on March 9, 1916, President Woodrow Wilson federalized National Guard units for border security, including the California National Guard, which began deploying to positions along the California-Mexico border on July 1, 1916.[11][12] Approximately 4,000 California Guardsmen conducted patrols, constructed fortifications, and enforced quarantines amid tensions from the Mexican Revolution, serving until their recall in February 1917 to prepare for potential European involvement.[11] This mobilization tested the Guard's logistical readiness, with California's units achieving rapid assembly and rail transport under federal command, though challenges like equipment shortages highlighted pre-war deficiencies.[11] Following the U.S. declaration of war on Germany on April 6, 1917, the California National Guard was fully federalized under the National Defense Act, with its infantry regiments forming the nucleus of the 40th Infantry Division, activated on September 16, 1917, from California, Nevada, Utah, and other Western states' Guard units.[13] The division underwent training at Camp Kearny, California, before sailing to France in August 1918, where it entered combat during the Oise-Aisne Offensive and the Meuse-Argonne Offensive, advancing against German positions in the final months of the war. By the Armistice on November 11, 1918, the 40th Division had incurred 2,587 killed in action, 11,596 wounded, and significant non-battle casualties from disease and exposure, reflecting the Guard's transition from state militia to expeditionary force amid high operational demands. Demobilized by early 1919, surviving units reorganized under state control, incorporating lessons from federal service into interwar training focused on mechanization and aviation support. The California National Guard's next major federal activation occurred on March 3, 1941, when the 40th Infantry Division was called into active duty for pre-war mobilization under the Selective Service Act, six months before Pearl Harbor.[14] Initially training at Fort Ord, California, the division deployed to the Pacific Theater in July 1943, participating in amphibious assaults and jungle warfare during the Bismarck Archipelago Campaign and the Southern Philippines Campaign, including the liberation of Leyte in October 1944 and Manila in 1945.[14][15] Elements of other California Guard units, such as the 7th Infantry Division's artillery and support components, reinforced Pacific operations, contributing to over 10,000 casualties across the division by war's end, with campaigns marked by intense close-quarters combat against Japanese forces.[15] The Guard's federalization left state defense to a newly formed California State Guard in 1941, but National Guard personnel remained integral to overseas efforts until inactivation in December 1945.[14]Post-World War II Reorganization and Cold War Era (1946–2000)
Following World War II, the California National Guard was reorganized to rebuild its strength and structure under federal recognition guidelines established by the National Defense Act amendments. Units began receiving federal recognition starting June 30, 1946, with many California Army National Guard elements, such as infantry and artillery battalions, reformed to align with post-war Army Table of Organization and Equipment standards.[16] By 1947, local units like the Salinas headquarters company were reconstituted as part of this effort, emphasizing rapid reconstitution for potential state or federal missions.[17] The onset of the Korean War prompted the largest federal mobilization of the California National Guard during the early Cold War. On September 1, 1950, the 40th Infantry Division was called to active duty, with approximately 10,000 Guardsmen undergoing training at Camp Cooke (now Vandenberg Space Force Base) before deploying to Korea in early 1952. The division participated in operations including the defense against Chinese offensives near the Punchbowl and Heartbreak Ridge, earning campaign credits for four major engagements before returning to state control in 1954.[13] Supporting units, such as the 980th Field Artillery Battalion, provided critical fire support throughout the conflict. During the 1950s and 1960s, the Guard focused on Cold War readiness, including adoption of the pentomic division structure in 1957 to enhance nuclear-era mobility and firepower. The California Air National Guard contributed to air defense, with squadrons like the 115th Air Transport operating C-97 Stratofreighters for strategic airlift. In response to the Berlin Crisis of 1961, the 115th was federalized from October 1961 to August 1962, supporting troop movements to Europe amid heightened Soviet tensions. Domestically, the Guard was frequently activated for civil disturbances reflecting urban tensions of the era. In August 1965, Governor Pat Brown mobilized over 13,000 Guardsmen to Los Angeles during the Watts riots, where they assisted law enforcement in restoring order amid widespread arson and looting that caused 34 deaths and over $40 million in damage.[18] Similar deployments occurred for the 1969 People's Park protests in Berkeley, where Guardsmen enforced curfews and protected property against violent clashes.[14] Vietnam War involvement remained limited compared to Korea, with no major unit deployments due to political sensitivities around Guard call-ups; only individual volunteers from California units, totaling fewer than 100 from the state Guard overall, served in Southeast Asia.[19] Reorganizations continued into the 1970s, including the 1974 inactivation of the 40th and 49th Infantry Brigades to streamline into modular brigade combat teams under Total Force Policy concepts.[20] By 2000, the California National Guard had evolved into a dual-state/federal force emphasizing disaster response training alongside conventional warfare preparedness, with the Air Guard transitioning to F-16 fighters for air sovereignty missions.[21]Post-9/11 Deployments and Modern Operations (2001–Present)
In the immediate aftermath of the September 11, 2001, terrorist attacks, the California National Guard was activated for domestic security operations under federal authority. Approximately 700 members were deployed to secure airports throughout the state, augmenting federal efforts to protect critical infrastructure. By early October 2001, an additional 2,000 Army National Guard personnel were placed on alert for potential mobilization in support of national defense priorities.[22] The Global War on Terror marked a period of unprecedented federal activations for the California National Guard, with units deploying extensively to Iraq and Afghanistan. Beginning in 2003, elements including the 1-184th Infantry Battalion, 579th Engineer Battalion, and 270th Military Police Company participated in Operation Iraqi Freedom, conducting combat patrols, base security, and infrastructure support amid insurgent threats. By mid-2006, over 11,000 personnel had been mobilized for these overseas missions, reflecting the Guard's integration into sustained rotation schedules. The 1st Assault Helicopter Battalion executed three deployments starting in 2004, providing aviation support with UH-60 Black Hawk helicopters. In Afghanistan under Operation Enduring Freedom, a California-led, three-state medevac unit completed multiple tours, including a 2014 rotation that involved over 3,000 flight hours and 683 patient transports.[23][24][25][26] These operations resulted in significant casualties, with 31 members killed in Iraq from 2003 to 2007—primarily from improvised explosive devices, ambushes, and vehicle accidents—and 3 in Afghanistan between 2009 and 2011 due to similar causes. By December 2013, California National Guard members had accumulated over 40,000 individual deployments in support of counterterrorism efforts worldwide. Post-2014, focus shifted to Operation Inherent Resolve against ISIS, with the 40th Infantry Division and other units providing advisory and logistical roles in Iraq and Syria. As of June 2025, approximately 205 Guardsmen remained deployed to U.S. bases in Qatar and Iraq for ongoing theater security cooperation.[24][27][28]Organization and Components
California Army National Guard
The California Army National Guard (CA ARNG) serves as the land force component of the California National Guard, maintaining a dual state and federal mission to respond to emergencies within California and deploy for national defense operations. Authorized for approximately 18,000 personnel, it operates under the California Military Department and reports to the Adjutant General of California for state activations, while federalized units fall under U.S. Army command.[29][8] Headquartered at the Joint Forces Headquarters in Sacramento, the CA ARNG is led by Major General Jeffrey D. Smiley, who assumed command on May 1, 2022, and oversees training, equipping, and readiness for all assigned units.[30][31] Key combat units include the 79th Infantry Brigade Combat Team (IBCT), based in San Diego, which consists of infantry battalions such as the 1st Battalion, 160th Infantry Regiment and 1st Battalion, 184th Infantry Regiment, along with the 1st Squadron, 18th Cavalry Regiment for reconnaissance and the 1st Battalion, 143rd Field Artillery Regiment for fire support.[32][33] The CA ARNG also supports the 40th Infantry Division headquarters in Los Alamitos, providing mechanized infantry and armored elements, as well as aviation assets through the 40th Combat Aviation Brigade, which includes assault helicopter battalions like the 1-140th Assault Helicopter Battalion.[34][35] Sustainment and support formations encompass the 115th Regional Support Group for logistics and the 1106th Theater Aviation Sustainment Maintenance Group for aircraft maintenance, ensuring operational sustainment in both domestic and overseas roles.[34] Special operations capabilities are provided by Company C, 1st Battalion, 19th Special Forces Group (Airborne), tasked with missions including unconventional warfare and foreign internal defense.[36] In the San Francisco Bay Area, key units include the 223rd Military Intelligence Battalion (Linguist), headquartered in San Francisco as part of the 300th Military Intelligence Brigade, providing linguistic and intelligence support.California Air National Guard
The California Air National Guard (CA ANG) serves as the air component of the California National Guard, comprising more than 4,500 personnel across five primary wings tasked with delivering air, space, cyberspace, and support capabilities.[3] These units fulfill dual missions: supporting the Governor of California in state emergencies such as wildfires and earthquakes, and augmenting active-duty U.S. Air Force operations for federal defense and combat requirements when mobilized.[37][3] Commanded by Major General Steven J. Butow, the CA ANG maintains readiness through training at strategically located bases throughout the state.[3]| Wing | Base Location | Primary Mission | Key Equipment |
