I am a little bias but have seen my buddies in their 4wd Rangers do some pretty amazing things with slightly larger tires. If you have any questions (owned mine for 10 years and know a thing or two about them) I'd be happy to help. Also, thanks for your service. My dad is retired Navy (Senior Chief), my mother is a Master Sgt in the Nc Guard (active duty), and the company I work for mainly takes jobs at Camp Lejeune, Cherry Point, and Fort Bragg.
Thanks been looking at a couple rangers. I've had good luck with them and I've gone some pretty intense places with stock tires but bigger is always better
