OOC: Assuming tactical, since he seems to have made that choice by sticking with Pavlov for so long.

Of course, it's entirely up to you; the six classes (a.k.a. "Divisions") are: Command, Tactical, Engineering, Medical, Science, and Flight. Etain's likely Medical, since that multi-classes to Counseling later on (though to be fair, I don't expect to put her in combat, like, at ALL), Kojan (a LZP character who hasn't shown up here) is Command (especially since, within the PCG, Kojan was a Council Member for a while), and pretty much everyone else seems to be going Tactical.

The bolter bullets are basically miniature rockets, with four small thrusters in the back of the bullet that fire off in a way that makes the bullet spin. The bullet is tipped with titanium, the same stuff used for the hulls of most ships. Behind the tip is a chamber of explosives. Behind that is the rocket fuel.
Basically, a squad of marines all armed with bolters can take out a light vehicle within a few minutes. Don't even ask about what it does to infantry.
Anyways, Yaka is a Terran company, and has only gotten big in the last few years after they won a contract with the navy..
