Operation Spartan Shield is the U.S. Army’s ongoing military presence across the Middle East, run by U.S. Army Central under U.S. Central Command. Its job is to deter aggression in the region, train partner militaries so they can handle their own security, and keep American forces ready to respond quickly if a crisis breaks out. At any given time, about 10,000 soldiers support the mission, and National Guard and Army Reserve members make up more than half of them.
Who Runs the Mission
Day-to-day execution belongs to Task Force Spartan, a multi-component headquarters combining active Army, National Guard, and Army Reserve units.1U.S. Army Central. Task Force Spartan It was stood up in August 2016, when the 29th Infantry Division deployed to Camp Arifjan, Kuwait, to serve as the division headquarters.2Virginia National Guard. 29th ID Returns to USA After Spartan Shield Rotation

Where Forces Operate
The operation spans USCENTCOM’s area of responsibility in Southwest Asia. Camp Arifjan in Kuwait is the headquarters. Camp Buehring, also in Kuwait, functions as the main training and logistics hub, where units run live-fire evaluations and other exercises.3U.S. Army Central. 28th Infantry Takes Over Task Force Spartan Other key sites include Prince Sultan Air Base in Saudi Arabia, the Jordan National Training Center, Muwaffaq Salti Air Base in Jordan, and installations in Iraq.
Training and joint exercises reach across the Gulf Cooperation Council region, involving Kuwait, Jordan, Egypt, the United Arab Emirates, Saudi Arabia, and Kazakhstan.5The United States Army. Soldiers Complete Successful Mission in Support of Operation Spartan Shield
What the Mission Aims to Do
Three overlapping goals shape the operation. Keep a credible U.S. presence in Southwest Asia to deter aggression. Build the capacity of regional militaries so they can handle security challenges without relying on American forces for every operation. Stay trained and positioned to respond fast if a conflict erupts.1U.S. Army Central. Task Force Spartan
Most of the work sits in that second bucket. Task Force Spartan pursues regional self-reliance through theater security cooperation activities: key leader engagements, joint exercises, conferences, and humanitarian-assistance planning.4National Guard.

What a Rotation Actually Looks Like
Joint and multinational exercises are the daily reality for deployed units. During a typical rotation, a headquarters participates in more than 15 exercises and numerous engagements with eight or more partner nations.2Virginia National Guard. 29th ID Returns to USA After Spartan Shield Rotation These range from tabletop command-post drills to full-scale combined-arms live-fire training. Eagle Resolve, running annually since 1999, is the premier multinational exercise in the Gulf, bringing U.S. and Gulf Cooperation Council forces together to train on border security, counterterrorism, and chemical-threat response.6The United States Army.

Brigade combat teams rotating under Task Force Spartan spread out across multiple countries. One brigade completed 12 separate exercises in six nations during a single rotation, working with land forces from Kuwait, Jordan, Egypt, the UAE, Saudi Arabia, and Kazakhstan.5The United States Army.

Air and missile defense integration is another significant piece. Army Air Defense Artillery Fire Control Officers coordinate between ground-based Patriot batteries and Air Force aircraft flying defensive counter-air missions, deconflicting fires across a joint kill chain so ground and airborne assets don’t interfere with each other in an engagement.7The United States Army. Spartan Shield, the Art of Air and Missile Defense Integration That kind of cross-service coordination is hard to practice at home stations, which is part of why the live theater environment matters.
Deployment Length and Train-Up
National Guard divisions typically serve nine-month deployments as the Task Force Spartan headquarters, but the full commitment runs much longer. The 29th Infantry Division’s headquarters staff spent over two years training before their nine months in theater.2Virginia National Guard. 29th ID Returns to USA After Spartan Shield Rotation For Guard members balancing civilian careers, the ramp-up means weekend drills, annual training periods, and certification exercises that grow more demanding as the deployment date approaches.
Brigade combat teams and smaller units follow their own timelines, with some battalions handling fire support or force protection while others focus on advise-and-assist missions or route clearance.5The United States Army.

Pay and Tax Benefits for Deployed Personnel
Because most of the OSS area sits inside designated combat zones or imminent-danger-pay areas, service members qualify for extra pay and significant tax breaks on top of base salary.
Hostile Fire Pay and Imminent Danger Pay together provide up to $225 per month. A member who actually comes under hostile fire receives the full $225 for that month regardless of how many days served in the area; those in designated imminent-danger areas receive $7.50 per day up to the same $225 cap.8Office of the Law Revision Counsel. 37 USC 310 – Special Pay: Duty Subject to Hostile Fire or Imminent Danger Service members separated from their families for more than 30 continuous days also draw Family Separation Allowance at $250 per month.9Defense Finance and Accounting Service. Family Separation Allowance
The combat zone tax exclusion is usually the biggest financial benefit. Under Executive Order 12744, Iraq, Kuwait, Saudi Arabia, Oman, Bahrain, Qatar, and the United Arab Emirates are designated combat zones, and the Sinai Peninsula of Egypt receives the same treatment for tax purposes.10Office of the Law Revision Counsel. 26 USC 112 – Certain Combat Zone Compensation of Members of the Armed Forces Enlisted members, warrant officers, and commissioned warrant officers can exclude all of their combat zone pay from federal income tax. Commissioned officers face a cap tied to the highest enlisted pay rate plus imminent danger pay, which for 2025 comes to $10,983 per month.11Internal Revenue Service. Publication 3 (2025), Armed Forces’ Tax Guide Over a nine-month rotation, that exclusion can add up to thousands of dollars in tax savings.
