Type-21 Heavy Assault Vehicle

The Type-21 Heavy Assault Vehicle, also known as the Hecate, is a Vehicle manufactured by CovTech for the Sovereign Covenant Empire along side the Type-97 Superior Assault Platform and the Type-19 Stealth Transport vehicles. It is essentially a Covenant version of the UNSC's Elephant.

Design
The Hecate is similar to the UNSC Elephant though in a Covenant fashion, and with the front being completely closed in along with the top. Infact, only a small troop hatch in the rear is a possible way into the vehicle. On the top are three Class-2 Energy Guns. One is on the side of the cockpit, while the other two both are in the back. Inside of the troop bay is a small slope heading into the cockpit, and beside that is a small area to allow for Maps of the planet and surrounding environment and to plan for attacks like in a base. Behind that is the Engine and Power core of the Vehicle, which is on the Elephant would be the open front. The Engine and Power Core are similar to that of the Scarab, if they are destroyed the vehicle will self-destruct.

Uses
Though it was intially designed and named to be a Heavy Assault Vehicle, due to it's weaponry the Hecate is a very slow attacker. It moves at a similar speed to a Wraith thanks to it's engines, however, which makes it able to arrive to battle a good enough pace. However, due to it's massive Size not many are often deployed into battle. Often only one will be seen in an important battle, with another being many miles away in said attack. Like the Mantis, it is often used as a mobile base, though the Hecate is used as such less often, given how little they are deployed. On Merciful Absolution, they are often seen around the lower streets being used as the primary transport for CovTech's own security soldiers and gaurds. They are also used as transport for the Hierarch's very own Bodyguards should they need to arrive in defense of the Holy Sanctum. During the major battles of the Sovereign Covenant Empire, they are often used near the Starting point of the Attack or Battle, and often are not seen very far from the attacking ships they are deployed from.
