I retired out of active duty so I don't know how IRR retirement works but a college asked me this question as I'm the only other former Navy doc that works in the local surgical center and I don't have a good answer for him.
So he is an anesthesiologist and got out after 15 years active duty to take a pretty lucrative position in the civilian world. He didn't want to completely waste the active time so he went IRR and he could take courses to add to his years without adding more rank or money but at least preserve the 15 years he did have for retirement income when he turned 60.
He is now at 19 and 1/4 good years both active and IRR combined.
Well, he got hit with an in person muster and in the last few years he'd gained some weight and now he's afraid that he'll lose his retirement because he's now overweight.
I told him that he'd better check with someone in the know, but when I was active duty, if someone was a fatbody at 19 years, they'd just let him retire because it would take less time for him to retire than it would take to board him out. It would take two PT cycles (1 year) to board someone out for overweight and at 19 years, you are already pretty much on the way out.
Opinions? Am I right or wrong?
