not a military guy but have buddies who are. I would pick (if avail) a busy VIP platform aka C-21 or heavy civilian cargo equivalent that is busy, aka KC-10, C-135, C-40/P-8 platform and see the world and build hours. Try to become IP or Stan/Eval pilot in said busy platform to make yourself "needed"
I think "cargo and pax" (especially VIP's) will always need air transport (job security for you) while some of the combat platforms (A-10 situation) may have reduced utilization or fleet reduction. Not sure how many hours annually an F-35 or F-22 guy is gonna get. Compared to a guy flying a cargo platform.
I am talking future, not today. aka - what platform if my question is : "I want to fly as much as possible for next 10-15 years in the military" and "after the military I want to fly for the airlines"
Just my opinions
