The military pretty much follows FARs, and where they don't, they're more strict. I'd expect the military does either 100 hour or progressive inspections, hour defined as "time in service" which for most aircraft is flight time as measured by a landing gear squat switch. Many general aviation aircraft will use tachometer time where they don't have such an flight time meter. Progressive inspections pretty much are 100 hour inspections but get broken down to e.g. 4 inspections every 25 hours, and the 100 hour inspection is only considered complete once the last inspection for that cycle is done. But they could do 10 inspections every 10 hours, or whatever.
