Hey Bud,
I did 6 years in the Marine Corps and did 4 deployments overseas. I got out of active duty in 2010, it was during my last DET in Afghanistan when I was diagnosed with UC. I still have been able to do the reserves but unfortunately I will not be able to re-enlist due to UC and injuries I sustained in a motorcycle accident this year.
I hate to be the bearer of bad news and I hope I am wrong in this instance (if the army is a dream if yours) but, if you've already been diagnosed with UC and opt for the surgery usually you can try to persuade (with the backing of your command) to let you stay in (depending on how bad you suffer from the disease). They might switch to something like admin and put you on a non-deployable status. I've also read that if diagnosed with UC and if you have not had any symptoms in over a year you can go in. Usually though anything involving major life-altering surgery of any kind is a disqualifier. Not because you cannot handle any of the training but because the military does not want to be held liable if anything happens, also the disability compensation that follows. I have also heard of people signing waivers on certain medical conditions relieving the military of any future responsibility.
My point is, while I do know UC is a disqualifier the j-pouch is an interesting thing. I still think that's a disqualifier but you never know. Also, keep in mind 99% of people don't know what UC is let alone surgeries that are undergone to get rid of it. Things are on a case by case basis depending on the recruiter.
A close buddy of mine just finished a tour of recruiting duty out of Tallahassee, Florida so I'll ask him and check back in for you. Either way talk to a recruiter over the phone. Good luck.
