Fort Benning

Some units have special callsigns they use when travelling out of area so the number used may not correlate with the 81/91 system. Normally, fighters use callsign + 11, callsign + 21, etc. One explanation I’ve read (which makes sense to me) is that the first unit sortie of the day is callsign + 11, the second sortie is callsign + 21 and so on. ................
