The band 30-88 MHz is used by the military, primarily Army, for ground and air tactical training communications throughout CONUS using a wide variety of tactical FM radios. Bands within 30-88, such as civilian land mobile bands between 30-50, the Amateur Band 50-54 and TV Channels 2 through 6 (54-60; 60-66; 66-72; 76-82; 82-88) are used on a noninterference basis to civilian licensees following coordination with FCC district offices. If you're around an installation with tactical units, e.g., Forts, Hood, Bragg, Sill, Polk, Irwin, et al, you'll hear ground, air-air, and air-ground communications in portions of the 30-88 band, with especially heavy traffic during training exercises. At some forts, FM freqs are permanently assigned to air traffic control facilities for occasional communications with tactical aircraft.
I have no idea what scanners are available that cover 30-88, but that info should be easy enough to find out.
