Yesterday, the Air Force bid adieu to the ABU, the Airman Battle Uniform, which was first introduced in 2007. The ABUs were “about as stylish as a fat collar and polyester bell-bottoms,” remarked one airman. Another said the ABUs were great “when I wanted to blend in with concrete.” The new uniform, called the OCP for Operational Camouflage Pattern, is easier on the eyes.
