Zurdo-pattern Wraith
From Halopedia, the Halo wiki
The Wraith is the main heavy vehicle of the Covenant army, and it is considerably different from the Scorpion Tank used by the Humans. It weighs approximately twenty tons, and, while packing less firepower, can move much faster.
The Wraith has two weapons, a plasma mortar, and anti-personnel plasma auto-cannons. The main plasma mortar launcher fires a ball of blue plasma approximately one meter in diameter into the air. Unlike the blasts from the Scorpion Tank, the moratr is affected by gravity, meaning that the shots 'arc'. This can be used to hit enemies behind cover.
The secondary weapon, the plasma cannons, are almost identical to the common plasma rifles carried by foot soldiers. The turrets will attack any enemy which comes within range, though they are not very accurate. However, they can take down energy sheilds relatively easily. This makes boarding a Wraith slightly more difficult. Oddly, the auto-cannons cannot be used by Humans, only Computer A.I. players. This makes them enitrely useless when a player is controlling the Wraith.
The Wraith also has a booster engine, capable of tripling the tank's speed for about one second. Once it is used, it takes about five seconds to recharge. Though this can be used to travel more quickly, it is commonly used to run over enemies who are getting to close. It can also flip small vehicles, such as Ghosts or Warthogs.
