So, like, screw all the guys from the 2515th? I guess 6ish years of no shit CASEVAC don't count?MEDEVAC would give you a little related insight into the PR/SOF MEDEVAC/CASEVAC roles. The other branches don't do business the way we do (units tend to be specialized since they sort of have that luxury) so it would be difficult to get the 'all-encompassing' exchange tour but getting a slice of the pie will give you a pretty good idea of how the rest of it tastes.
I still, after reading a lot of your posts, have no idea what you want. Everyone cannot do a tour with the 160th, HMLA, Army MEDEVAC, USAF Pararescue, Navy SWTI, then come back to teach the nuggets "how it's done".
