Any reason why there are no military tower frequencies (at least in the US)? Federal Law prohibiting this? They are public frequencies, in the sense they are published on aeronautical charts and sites like AirNav.
Military frequencies are definitely available. If you are seeing them on sites like AirNav, then you are seeing that they are public, as they are published on FAA charts. The 4 AFBs I worked at all have frequences listed: Wright-Patterson, Offutt, Nellis, and Tinker.
In fact, the only AFB I know of that doesn't have a frequency available on any chart whatsoever is Los Angeles.
