It's hard to say what weapon as I don't quite know which of the many units on the field in a game of Dawn of War 2 represents me. Presumably it would be the commander, which means usually I'd get the plasma cannon but thanks to the fact I was playing against a pair of Tyranid players I was still using a bolter (the higher rate of fire was more useful than the higher damage of the plasma rifle).
That basically means that I'm boned. I couldn't even hope to carry a full sized bolter much less survive firing the damn thing. Hell, the bolt pistol is large enough that it looks like a very cumbersome SMG when made to scale.
On the plus side, I do have a Carnifex on my side so I think I'll do juuuuuust fine.
