I'm in a nasty situation on solo campaign where I have to face off against a pair of Mgalekgolo (hunter, mechanized infantry – the guys with the giant green ball cannons and shield) in a single-elevation room, and I can't figure out a strategy for killing them. I know I can assassinate them effectively if I can get behind them, but while there are a lot of obstacles in the room, I can't figure out how to get into that situation. Is there a way to kill them without using the knife? They laugh off grenades and I haven't been able to find a spot for a head shot with the DMR (I have access to a DMR, Machine Gun, Shotgun, and a few small caliber covenant weapons).

The answer appears to be 15 to 20 "face shots" with the DMR. I'm not sure if that's what just magically ends up being enough to get a head shot at distance, or whether they really start losing HP. The shots were basically directly to the face, they will bring up their shield immediately after (so don't just hammer on the trigger), and then drop it again and you can take the shot again. Just keep doing it until they fall over.
