The Air Force has made some seriously boneheaded uniform decisions. The last one, the Airman’s Battle Uniform, was possibly the most ironic uniform ever developed. It was so bad in battle, airmen who went outside the wire were given a different garb to wear when they accompanied a QRF or patrolled off-post.
Benjamin Franklin nailed it when he said, "Fatigue is the best pillow." True story, Benny. There's nothing like pushing your body so far past exhaustion that you'd willingly, even longingly, take a nap on a concrete slab.
