Halo 2: Hint - Tank Weak Spots

The two tanks in Halo 2 have different weaks spots (and strong points). The human Scorpion tank has a turret that is almost invincible; it's naturally vulnerable in the body and the four tread motors (which count against its hull integrity).

The alien Covenant Wraith has a very strong glacis (the front armored bulge where the pilot is). Consequently, it has a very weak rear.

Rockets affect both tanks as if the weakest facing is used, meaning two shots will knock out any tank.
