Ghar engineers don't dabble with any other technology other than their own, because of this they have nearly perfected their own weaponry with which they annihilate their targets. A single high powered shot from the mag cannon can pierce through almost any armour both infantry and vehicle alike, just choose your target and watch them get obliterated.
