2nd Infantry Division (United States) The 2nd Infantry Division ("Indianhead"; "2ID," "2nd ID", or "Second D") is a formation of the United States Army. Its current primary mission is the defense of South Korea in the initial stages of an invasion from North Korea until other American units can arrive. There are approximately 17,000 soldiers in the 2nd Infantry Division, with 10,000 of them stationed in South Korea, accounting for about 35% of the United States Forces Korea personnel.
49th Quartermaster Group The 49th Quartermaster Group (Petroleum and Water) was a United States Army Forces Command (FORSCOM) combat service support unit stationed at Fort Lee, Virginia. The group motto was "Fueling the Force." Reactivated in 1993, the 49th held an inactivation ceremony at Fort Lee on 14 September 2012. Its subordinate 530th Support Battalion and 108th Quartermaster Company were reassigned to a brigade headquarters to await their own inactivation in September 2013. According to an article in the post newspaper, "The 54th and 111th, the Army's only active duty mortuary affairs units, are not likely to be inactivated but may be transferred. If any of the units remain at Fort Lee, they may be realigned under battalions either at Fort Eustis, home of the 7th Sustainment Brigade, or Fort Bragg, N.C., home of the XVIII Airborne Corps, the 49th's current higher headquarters."
