Kodiak artillery systems are armed with long-range siege cannons, though the vehicle must deploy before it can fire. Deployed Kodiaks cannot move, which means that they are best paired with other units to act as spotters. Professor Anders can fit the Kodiak with beacon warheads that act as Sentinel lures, attracting and antagonizing the Ark's defense constructs.
A modern UNSC vehicle introduced to the Spirit of Fire by Isabel, the Kodiak M400 Artillery System has quickly become a favorite of the ship's crew on account of the Kodiak's spectacular firepower. When the Kodiak enters lockdown mode, the articulated ‘feet' from the side of the vehicle fold down to anchor the vehicle to the ground to provide stability and counter the recoil of the siege cannon. The cannon's shells are massive and take some time to reload between firing, but the devastation they cause is well worth the wait.
