Although the Shade appears to be a light anti-vehicle weapon, the Covenant uses it almost exclusively in an anti-infantry role. The operator sits directly behind the gun and an armored control suite, but relies entirely on infantry support for protection to the sides and rear.
A surprisingly powerful plasma weapon, the Plasma Turret (or "Shade") is an excellent anti-vehicle station. It also can be put to good use against infantry - its bursts of fully-automatic plasma fire will spread nicely at long ranges. However, this same spread also hampers accuracy and impairs your damage - it's advised to fire at close ranges when fighting vehicles. And your inability to move is a nasty disadvantage.
