[LA Noire] What exactly happened in boot camp with Cole Phelps?

There's a flashback in the game where everyone has to rate each other and then at the end of the flashback Kelso gets rated by Phelps and then he says he didn't join the corp for this school yard bullshit and storms out after having his weekend pass denied. What was that all about?

They were in OCS (Officer Candidate School), not boot.  It's implied that Kelso dropped out, being fed up with "this schoolyard chickenshit" and enlisted instead (where he'd actually go through "boot camp").

Hence Phelps outranks Kelso, as Phelps completed OCS and entered as a Lieutenant, whereas Kelso chose to enlist and entered as a lowly Private.
