Light Armored Vehicle or LAV crewmen operate and maintain the LAVs and their weapon systems. These vehicles are eight-wheeled and amphibious. They're armored reconnaissance vehicles that can carry communications equipment. The name of the position is something less than politically correct in this day and age because a LAV crewman can be male or female.

The Role of a LAV Crewman 

The LAV's role within a larger Marine expeditionary unit or MEU is to conduct security, recon, and screening missions for a larger force along with some independent operations.

 The military occupational specialty for the job of LAV crewman is MOS 0313. It's considered a primary MOS. 

The LAV Crew

LAV crewmen must have gunnery skills to operate the LAV weapons. These include the 25 mm chain gun, the coaxial and pintle-mounted 7.62 mm machine guns, and thermal optics on the LAV-25 variant. They're typically well-trained in security and recon missions as well. Non-commissioned officers can be assigned both as LAV vehicle commanders and LAV 25 gunners. 

LAV crewmen include the LAV Driver, who maintains the LAV engine and hull components. He or she drives and operates the vehicle and maintains the vehicle as a stable platform from which the gunner can engage targets. The LAV gunner maintains the turret and components of the LAV weaponry and employs its weapons. The LAV commander supervises all maintenance and operations of the LAV, as well as assuming leadership and responsibility for the vehicle and the crew as a whole.

Each LAV vehicle has three crew members: the vehicle commander, the gunner, and the driver. An additional four passengers wear combat gear.
