Yes mate, I think this is very important to consider in order to give the game a believable atmosphere and enemy culture. Having said that, I'm not sure if a space game is the right place for that kind of logic.
In Quake, you're dealing with fairly lawless alien nuttjobs with a clear heirachy and probably a culture of beating the shizzle out of each other. Therefore its quite believable and cool when the big ones smack the little ones down. In a space game, you're talking about highly intelligent qualified space pilots flying about in high tech bits of kit. To turn around and gun each other down because of one or two stray shots is pretty stupid and unrealistic. I'd be much more convinced with radio chatter like "CHECK YOUR FIRE!!!" etc. rather than killing a teammate and a multimillion dollar fighter!
Btw, the game looks great btw.
