A handmade Christmas tree welcomes Marines with 1st Marine Division to the Division (Forward) headquarters field mess aboard Marine Corps Air Ground Combat Center Twentynine Palms during Exercise Steel Knight 14 Dec. 14, 2013. The field mess served two hot meals each day during Steel Knight, which enabled 1st Marine Division to test and refine its command and control capabilities by acting as the headquarters element for a forward-deployed Marine Expeditionary Force.
