This came up while looking for ANG aircraft colors and markings; I have never seen the document in its entirety before, and I thought it might come in handy for those of you doing USAF/ANG aircraft. Covers aircraft through 1998, apparently. Lots of useful information on colors, markings, and insignia for exteriors and wheel bays.
