The M1000 Tiger Heavy Battle Tank is one of the largest and most powerful vehicles in the UNSC Arsenal. With a 120mm guns, two .50 chain gun turrets on the turret and one by the driver at the front, along with a small battery of anti-air missiles it was long considered a joke by the UNSC. Only three prototypes were made during the Human-Covenant war, two of which were given to the army, after most were declined by the Marines due to the fact it cannot be airlifted by Pelicans or Albatrosses. The prototype at the time was slow, cumbersome, prone to engine failure and a easy target. however, on it's side, its armour was nigh impenetrable to Covenant small arms and their vehicle based weaponry. Two never saw action but the Marine's Tiger prototype saw action during the Second Battle of Earth.
