Operation Enduring Freedom - Afghanistan [OEF-A]
US Forces Order of Battle
6 August 2010

These orders of battle represent a "best available" order-of-battle of forces deployed in CENTCOM's part of Central Asia in support of Operation Enduring Freedom in Afghanistan. The amount of publicly available information concerning aircraft types and specific units makes it difficult to provide a high fidelity profile of deployments "current" to the stated timeframe of the order of battle. There are likely significant gaps in unit identifications, as well as non-trivial uncertainties as to numbers of specific types of aircraft. The presence of significant numbers of civilian contractor personnel at various facilities in the region further complicates accounting for total personnel numbers.

Recent Developments

In July 2010, the 1st Brigade Combat Team, 4th Infantry Division began deployment as scheduled in support of Operation Enduring Freedom in Afghanistan. The Brigade Combat Team was deployed to support the training and mentoring of Afghanistan security forces. As of August 2010, it was unclear where the Brigade's headquarters would be located.

On 14 June 2010, the newly activated Regional Command South West (RC-SW) formally took command of ISAF forces in its area of responsibility. The new organization provides improved oversight of ISAF forces operating in Helmand and Nimroz Provinces. With the majority of ISAF forces based in southern Afghanistan, the formation of the new headquarters permits commanders in the south to focus on geographically smaller areas, ensure greater partnering between the Afghan National Security Forces and ISAF, and deliver the levels of security required for governance and development to continue to spread in the region.

The Department of Defense announced on 27 May 2010, the alert of replacement forces scheduled to deploy in support of Operation Enduring Freedom.

The units would replace redeploying units, with no increase in overall force levels. They were scheduled at that time to begin their deployment in the summer of 2011 and were receiving alert orders then in order to provide the maximum time to complete preparations. It also provided a greater measure of predictability for family members and flexibility for employers to plan for military service of their employees. The 37th and 45th Brigade Combat Teams would deploy to Afghanistan to conduct counterinsurgency operations in partnership with the Afghan National Security Forces.
