Eh, I believe they arrived after the Battle of Earth. They hadn't necesarrily graduated yet during the events of Ghosts of Onyx- they were still competing for Top Honors, hence the extra 15 that stayed behind on Onyx.
The remaining teams probably started a voyage to the next-closest human planet (as far as we know, Earth was not the only human planet left standing by the end of the War. It's strongly hinted at that other inner-colony planets may have been bypassed). My guess is they arrived at Earth post-war and were probably imperative to the physical labor of reconstructing the planet and were more than likely invaluable security forces.
It's either that, or they sent Gamma Company out to hunt for any in-system Covenant remnant forces.
Only three teams stayed on ONYX, probably teams Kurt was attempting to put into Noble-esque Spec Ops teams. The rest of the Company had already been deployed.
....I pretty much just said that. The 15 that stayed behind were the "three teams" competing for "top honors" which was probably Kurt's SpecOps assignment testing.
EDIT- I think you're keying on on them being 'deployed', yes? I'm too lazy to go pick up my book, but does it specifically mention them being deployed? Because as far as I'm aware, their being 'deployed' was never specifically mentioned.
