A lot of Commissars fight in the front. Forcing stupid decisions and shooting anyone who disobeys with these crazy, suicidal orders. He's got a lot of Commissar disdain behind him, regardless of how he actually is. Elou doesn't want to be shot for some percieved disobidience. Or for disobidience against some stupid order like 'I don't care if there is a literal ton of sand around, use your face to smother that fire!'. Elou prefers the ones in the backlines, because they can't shoot you right away, and there is a slight degree of control over what you can do. Can always Bullshit into the vox later.

It's 40k. Anyone not prepared for blood needs to go back to their MLP Rps.

And, Elou doesn't pay much attention to the group, so she factors practically all the shouting to the Commissar, even if he isn't actually the one doing it.
