The handy M19 60mm mortar was intended to replace the M2 60mm but suffered from weak range and accuracy issues.

The M19 60mm mortar (the US equivalent to the British 2-inch) was developed during World War 2 for infantry-level support actions to provide for a reusable, lightweight, high-angle of fire weapon system to replace the M2 mortars then in use. The M19 could be called upon to lay down "fire from above" and utilize a variety of conventional high-explosive and specialty munitions as the situation required. However, the light M19 suffered from being highly inaccurate when not fitted to a standard baseplate and, when fitted as such, became heavier than the M2 it was intending to replace - suffering shorter effective ranges as a result. Despite the intent, the M19 failed to live up to expectations and was ultimately replaced in the US Army inventory by the M224 system. The few M19s in use were mostly delivered to airborne elements that could make use of such a light weapon system and many were further exported to American-friendly nations of the time.

The M19, unveiled in 1942, was of a conventional mortar design by most respects and closely resembled the British 2-inch mortar family. The launch tube could accept projectiles of 60mm caliber with warheads to include high-explosive (HE), illumination and smoke rounds. The mortar crew was often charged with engaging dug-in enemies by raining munitions on or around them in an attempt to kill or dislodge. Beyond its lethal intent, the M19 could be called upon to "light up" the immediate battlefield at night or deliver protective "walls" of moving smoke to help conceal allied movements during the day. The crew actuated the M19 by dropping an armed projectile down the smoothbore muzzle (the M19 was a "muzzle loaded" weapon). The projectile's base would then contact the awaiting firing pin and enact the projectile's propellant, sending it across a pre-determined trajectory based on the elevation angle and traverse set by the mortar crew, eventually impacting in the target area. Muzzle velocity was rated at 550 feet per second while effective range was out to 5,870 feet (1,790 meters).
