The LAV-M was the LAV-25 with its 25mm gun turret replaced by a mount for the 81mm mortar. A three-section folding cover was installed over the mortar to permit firing from the vehicle. The commander was moved to a cupola directly behind the driver, and the machine gun was mounted at the commander's station. The smoke grenade launchers were attached to the hull roof since there was no longer a turret. The mortar crew was provided with a bench along the right side of the fighting compartment, and mortar ammunition was stowed along the opposite side of the rear compartment. The fuel tank was relocated from under the rear floor in the LAV-25 to the left side of the rear compartment.
The LAV-M underwent upgrades to -A1 and -A2 standard like the LAV-25.
