The M402 Multipe-Launch Mortar is a 70kg man-portable artillery weapon used by Marines of the USCMC. The mortar uses a 80mm twin-tube design, automatically fed from a ten-round rotary magazine. The weapon can be aimed and fired by a remote command handset, either singly or in volleys. All ten rounds can be fired in under eight seconds.
As part of their organic support weapons, the standard Marine rifle platoon is equipped with one M402 mortar. Though it can be carried and fired in the field, the M402 is also commonly carried by the M572 Armored Mortar Carrier.
