Light Armored Vehicle (LAV) crewmen operate and maintain the LAVs and their weapon systems. These vehicles, which are eight-wheeled and amphibious, are armored reconnaissance vehicles that can carry communications equipment. Note that despite the name of the position, LAV crew can be male or female.

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

 

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

The LAV Crew

The LAV crewmen need to have gunnery skills to operate the LAV weapons, which 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. 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, 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. And the LAV commander supervises all maintenance and operation of the LAV, as well as assuming leadership and responsibility for the vehicle and crew as a whole.

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

Initial Training for MOS 0313

In order to qualify for the job of LAV crewman, recruits need a general technical (GT) score of 90 or higher on the Armed Services Vocational Aptitude Battery tests (ASVAB), and have to be qualified as basic infantryman.

They'll need to complete training at either schools of infantry, or at the infantry training battalion (ITB) as a rifleman (MOS 0311).

They also need to complete the LAV crewman course for assignment as a primary MOS.

Marines seeking an MOS lateral move (LAT Move) to the MOS 0313 are still required to complete ITB training if they have not been previously qualified in an infantry MOS.

LAV crewmen must also be qualified as at least a fourth-class swimmer. They'll need vision of minimum 20/200 correctable to 20/20, and need the psychological and physiological qualifications required for licensing as a government motor vehicle operator. LAV crewmen should have a driving record that qualifies them for an SF-46 military driver's license. 

After recruit training, LAV crewmen will complete the infantry training battalion course, followed by the LAV crewman course at Camp Pendleton in California. The ranks for LAV crew members range from private to master gunnery sergeant.
