I wouldn't think yelling at you would, in any way, prepare you to do anything related to combat.Ah okay I see...Thank you again Jim!
It's interesting that they don't raise their voices anymore...especially during the chaos of combat or even a training mission where you have to deploy ordnance in a specific time.
In my experience, I always got along with the yellers because it would just make me laugh. Evidently the good ones got what they were looking for because usually they'd end up being cool with and actually teach you some good stuff.
