Airmen with the 647th Security Forces Squadron at JB Pearl Harbor-Hickam, Hawaii, tested their physical and mental stamina during a grueling two-day trial at the beginning of February 2011 in Wahiawa, Hawaii, to see if they have what it takes to attend a two-week air assault course that the Army's 25th Infantry Division and 25th Combat Aviation Brigade will sponsor in May 2011. Here, airmen take on the obstacle course during the trial, Feb. 1, 2011.
