I am spoiled in that I live/work within VHF/UHF monitoring range of all Nellis & NTTR aircraft operating above about 3000' (that's often everything but the Rescue Squadron & Special Ops helos) so I realize I'm spoiled in the amount of "Victor" band military aviation comms I hear, as well as the 225-400MHz stuff and the 30-88MHz "Fox-Mike" stuff that the A /OA-10s & helos like to use.
I do search 138-144/148-150.8MHz in AM & FM modes frequently, & predominantly what I've heard over the past decade, besides Civil Air Patrol & MARS, & USCG Aux has been military aircraft, in AM mode. The average flight (two or more aircraft flying together) will use UHF to talk to their controller (ARTCC, AWACS, FAC, TACP et al) but then a VHF 138-144/148-150.8MHz AM freq for 'interplane' comms, often a little bit of official traffic & a lot of BS'ing to pass the time, depending on what's going on.
The only time I've caught any tactical comms of interest in that spectrum using FM mode, once it was (apparently) Naval Criminal Investigative Service with an airborne surveillance, and once Air Force Office of Special Investigations with a ground mobile surveillance, both in the San Francisco Bay area. The Monterey Military Community PD (Defense Language Institute/Presidio of Monterey, Naval Postgraduate School & Ord Military Community) were on FM in that spectrum, and I seem to recall Naval Base Ventura County's LMR nets were in the 140s FM (as most Navy/MC LMR nets were) too.
