Recruit Camp is basically bits and pieces of BMOQ. (Lectures, PT, drill, inspection, uniform, written tests, etc.) Literally everything covered in recruit camp is covered in BMOQ. If you've done BMOQ, there wouldn't be any reason to go to recruit camp. HOWEVER, when my buddy did recruit camp he informed me that there were people who had done BMQ (through reserves, etc...) and they still had to do recruit camp, for some reason. I guess they hadn't done BMOQ, only BMQ, so for whatever reason someone felt recruit camp was necessary for them, as well as BMOQ the following summer.
As I understand it, it's basically a crash course in 'what you really signed up for, so get your *** in shape because PT is harder than high school gym class' for ROTP Civ U students.
I would guess that, if after enrolling in the ROTP, if you somehow get loaded onto a BMOQ course before doing recruit camp, you wouldn't have to do recruit camp. It's not a requirement for commission, or even a formal requirement for anything...I understand you get a letter saying you did recruit camp on your file...not a formal evaluation or anything that would normally be involved in a formal course...
