M370 autocannon

The 70mm chain gun is an anti-personnel/anti-vehicle weapon mounted below the nose of some D77-TC Pelican dropships.

Overview
The gun is linked to the movements of the pilot's head, which allows for very short delays between spotting enemies and firing, the turret will rotate up to 120 degrees to wherever the pilot is looking. However, the turret can also be operated by a copilot, or manually by a gunner.

This weapon fires very large 70mm shells. The rate of fire is most likely lower than most UNSC automatic weapons, though the shells certainly have heavy stopping power.
