The HAMR has two main weapons; a standard ISA .50 caliber M224 HOMAG machine gun and a high-explosive-armor-piercing 35mm autocannon, both linked on a single turret and controlled by a dedicated gunner. While lacking the sheer power of either the Archer's missiles or the main gun of a Lancer tank, the cannon compensates with a much higher rate of fire, and its repeated blasts can destroy all but the toughest Helghast vehicles.
