Not really. I wasn't a pilot, just a lowly ABF in the Navy. But when we deployed, on an LHD, most of our flights were what you could probably "classify" as training. We ran flight ops every day because pilots have to maintain hours. We flew every day for 7 months and only 2-3 of those months were we in the gulf. And even in the gulf, not all flights were missions, I would say less than half were. That also isn't counting 4-6 months prior to deployment of work ups where we would go out to sea for a week and come back, everyday pilots flew training missions off our deck. All in all, all in the military probably spend most of their air time training then actually flying missions.

I also recall, even experienced pilots, would rotate out to training units as their "shore" (break from a deploy able unit) duty.

This wasn't a Navy aircraft, but I imagine a lot of that is the same regardless of branch.
