This depends on your airframe mostly, but also the unit you are assigned to.
Home time is not home time. The typical aviation battalion can expect at least 1-2 CTC rotations in a year. If you are attack that also means 2-3 gunneries a year. if your battalion is super motivated, you'll do field exercises in conjunction.
I got home from Afghanistan, was home for about 2 months, then was at a gunnery for 2 weeks, was home two weeks, back out to a gunnery again for 2 weeks, home for a month, gone to JRTC for a month, then we were home for about 2 months before another gunnery, a SOF exercise, another SOF exercise and another gunnery. All told the average pilot in our company was gone 5 months out of this year away from station on training, in a "dwell" period.
Attack aviation is way undermanned and in demand at CTC rotations and other combined training events. There are training exercises overseas, with foreign governments, etc etc.
I've found I am busier and away from home way more than I was as a grunt. A year on a year off is way better than the current Optempo/quality of life, at least in attack aviation.
It is worth it though if you can survive to PC and track. If you want a home life and predictability - go guard/reserve
