M32 mortar

The M32 Infantry Support Weapon is the standard infantry-portable mortar adopted by the UNSC Army during the Human-Covenant War.

Design
While the UNSC Marine Corps has long embraced preprogrammed missile launchers to fulfil their indirect fire needs, the UNSC Army has still retained mortarmen in their order of battle for a multitude of reasons. Their inability to be jammed, portability compared to vehicle-mounted weapons, and the low cost of their ammunition are all compelling arguments for their continued use, and the Army brass believed that practicality and reliability should always take priority over the latest technological advances.
