A bipod is a V-shaped portable attachment that helps support and steady a device, usually a weapon such as a long gun or a mortar. The term comes from the Latin prefix bi- and Greek root pod, meaning "two" and "foot" respectively.
Most general-purpose machine guns, such as this FN MAG, have a bipod to increase accuracy for the full-automatic fire mode light machine gun fire support role.

A mortar is today usually a simple, lightweight, man-portable, muzzle-loaded cannon, consisting of a smooth-bore metal tube fixed to a base plate with a lightweight bipod mount and a sight. Mortars are typically used as indirect fire weapons for close fire support with a variety of ammunition. Historically mortars were heavy siege artillery. Mortars launch explosive shells in high-arching ballistic trajectories.
