ANNEX
Constituted 3 May 1861 in the Regular Army as Company B, 3rd Battalion, 17th Infantry. Organized 29 October 1865 at Hart Island, NY. Reorganized and re designated 21 September 1866 as Company B, 35th Infantry. Consolidated 12 August 1869 with Company B, 15th Infantry and consolidated unit designated as Company B, 15th Infantry. In 1996 the Division was re stationed at Fort Stewart, Fort Benning, and Hunter Army Airfield, Georgia. The Division repeatedly demonstrated its deployability since then by maintaining a battalion, and later a brigade task force presence in Kuwait. It has also moved sizable forces to Egypt, Bosnia and Kosovo in partnership training and peacekeeping missions. Since Sept 11, 2001 units have been sent to Afghanistan, Pakistan and other Middle Eastern countries to support the War on Terrorism.

Early in 2003 the deployability and fighting capability of the Marne Division was highly visible Worldwide when the entire Division deployed in weeks to Kuwait. It was called on subsequently to spearhead Coalition forces in Operation Iraqi Freedom, fighting its way to Baghdad in early April, leading to the end of the Saddam Hussein government imposed tyranny over the people of Iraq. Today the Division remains there contributing to stabilization and nation building with Coalition forces and the people of that long oppressed nation.
