A Marauder is a terran infantry unit that looks like this.
It is mainly used in Terran army compositions for additional damage against armoured units, the slow and a general meat shield since they are tanky.
Oh wait McMaster Marauder. They're the people who relay the ideals and goals of the student union to the general population, but are mostly there for spirit and enthusiasm. I like terran marauders better.
Also, bleeding maroon is bad. That's probably lack of hemoglobin in your blood or something. Might want to get that checked out.
