The M4131 is a 152mm indirect-fire artillery piece used for long-range bombardment. The weapon uses an electromagnetic catapult-assist system capable of launching standard 152mm high-explosive artillery shells or more specialised payloads. These include unmanned drones, precision-guided munitions, and beacon warheads designed by Ellen Anders to serve as "lures" for Sentinels. As such, the M4131 can be used to fire upon enemy positions and, once the shell has detonated, attract flocks of Sentinel automatons to continue harassing targets who survive the initial attack.
Some research into cryotechnology by Serina has additionally yielded a simulated cryonic shell for the M4131 howitzer capable of freezing units caught near its blast. This variant, like other cryotech investigated by Serina (such as the Frostraven or Tundra Bison projects), has presumably yet to see application outside of specialised simulations.
M4131 howitzers are predominantly used as long-ranged artillery mounted as the primary armament on the M400 Kodiak self-propelled artillery truck. They may also be employed as an optional weapon mounting on the M5 Talos automated defensive system - Talos-mounted M4131s are sometimes known as "siege turret"s, and can be deployed as part of the armament on a UNSC firebase or deployed from orbit to serve as artillery support.
