Frequently Asked Questions about the Airman Battle Uniform Published Aug. 14, 2007 EIELSON AIR FORCE BASE, Alaska -- Q1. Can we wear the green Airman Battle Uniform boot with all Air Force utility uniforms? If so, when? A1. Yes, you can wear the green ABU boot with all Air Force utility uniforms now. They are available for personal purchase (not issue or unit funded purchase) in AAFES, Military Clothing Sales Stores. The official authority, via 8106 message, will be forthcoming in late August, early September. The "Safe for Flying" green boot has successfully completed testing and production has begun. We expect to see these on the shelves in early Fall 2007. Q2. Why does it appear that there are shade differences with some sets of ABUs? A2. Some ABUs issued or purchased through AAFES, do appear to have some shade variances, but they are all within the shade tolerance specifications set by the Air Force. This is a normal development process that happens when a new uniform with a new textile is used. We anticipate that this will work itself out as the vendors formalize the process and produce more uniforms. The different shades variances are authorized.
