[@Andreyich] You're a heavy weapon specialist or have a Cadian pattern las-gun and bayonet like the rest of the grunts. If a specialist then you may choose a heavy weapon. For now.

[@NecroKnight] Yup!

[@Dannyrulx] Yes and yes, you'll probably get a company banner at some point too.

[@mackielars] Unless it's needed for a specific role I.E. Sniper, flamer etc, then yes.
