Operation Spartan Shield (OSS) is a United States Central Command operation in the Middle East. OSS is commanded by United States Army Central and includes units from all service branches. Task Force Spartan is the U.S. Army component of OSS.

On 19 December 2016, the 29th Infantry Division (United States) assumed command of U.S. Army Central's intermediate division headquarters, Task Force Spartan, at Camp Arifjan, Kuwait. This deployment includes 450 Virginia, Maryland and North Carolina Army National Guard soldiers and is the first time the 29th Infantry Division has been a part of the Third Army since World War II.

More than 80 members of the 29th deployed to Jordan in August 2016 where they assumed command of the military's joint operations center there to support Operation Inherent Resolve. Soldiers of the 29th led engagements and joint training with the Jordan Armed Forces and allied countries before returning in July 2017.

The 408th Contracting Support Brigade supports contracting requirements for Operation Spartan Shield, described in Army Lawyer as "USARCENT's steady state operation to Build Partner Capacity [that is, to conduct Capacity building) in the Middle East."

In Syria, on 25 August 2020, a Russian vehicle allegedly rammed a U.S. Mine Resistant Ambush Protected (MRAP) vehicle, resulting in a U.S. Army (Operation Spartan Shield) response.
