Members of the 219th Security Forces Squadron from left to right Airman 1st Class Angela Lage and Airman 1st Class Alex Pauling pass through a gate at a Minot Air Force Base, North Dakota, missile alert facility May 20, 2015, as they sweep the area for anything suspicious. The North Dakota Air National Guard members are doing their annual training period as they perform the real-World mission of missile field security, and train for their war-time tasking mission. The Air National Guard members are routinely integrated among the U.S. Air Force active duty personnel performing missile field security in a seamless and indistinguishable manner.
