The squad had four krag greandes among them, and a pair of frag grenades each.  Their autoguns were ugly and stubby, easily braced and supported by 2 reloads each.  Each mutant had a knife and a sidearm, usually a shotgun pistol or a hand cannon, but one of the mutants carried an autopistol as a sidearm instead.  The autopistol had an odd curved magazine giving it a small, easy to handle profile, and seemed to have been manufactured with the greatest care, bearing the mark of nurgle.
