Oh please, Plague, this is a fluff site and everyone knows that, in the fluff, no loyal Space Marine dies to a guardsman of any rank or weaponry. Sometimes an unnamed one dies when an entire army has gone against it.

Plot armour always protects the SMs, so stick to killing what you can, namely the smaller Tyranids and Orks.
