Well, I've never served in Kuwait, so I jump into this hornet's nest with reluctance, but I'll take a stab.
I did multiple tours in Yugoslavia, back in the day, with minimal financial rewards, but we did get extremely generous leave packages. I also did multiple tours in Afghanistan, with incredibly generous financial rewards, but the same leave packages. Honestly, in the second case, I liked the extra leave and HLTA more than the cash. But with the Air Force model of short deployments for aircrew, the members are getting the short end of the stick for both cash and leave.
But I can see RoyalDrew's point. My Grandpa deployed in 1939 for the duration (albeit with generous local leave in the UK while they were waiting for Overlord to kick off). Would I have been willing to sign on for a 3 or 4 year deployment to Afghanistan, so long as I got generous R&R and leave packages? Probably. KAF had a bigger population than Petawawa, and better shopping.
