I'd call it Trotteltrio

You may already know the guy in the middle - Louis Benson. The other two fellas are his best buddys. Philip O'Donnell on the left and Wes Maryland on the right. Great soldiers when they're on their own, a living disaster when they're together. They just tend to fuck things up and making situations worse, even (or especially) in combat.
In this pic they're carrying their favourite weapons. A sniperrifle for Phil (who IS a sniper), the beloved Seburos for Louis and a fat pumpgun for Wes.

This drawing was meant to be colored in Photoshop, unfortunately i never did so. What i dislike the most is Louis' face. It's just too... short I'd say.
