DTMG GAC bug????

I've just fought this squad of DTMG, Scout, Stormtrooper, Gideon and Death Trooper. 
How come there was the Dark Trooper in the fight added to their team (total 6)????

Too bad I didn't capture the screenshot, was not sure if it was in someone's kits but apparently I have yet to find any.
It was not a display glitch, he actually did jump across and punch though my Raddus.

CG If you have in-game logs, please check it out.
