Maintenance is the act of keeping a vehicle or other machine in top condition. Well-maintained vehicles last longer than average, and may tolerate conditions that a non-maintained vehicle might not withstand.

"Preventative maintenance procedures improve your vehicle's recovery from damage. This is active while in any seat of the vehicle."
— Battlelog description

Maintenance is a specialization for all vehicles that increases the rate at which armor regeneration occurs.

This does not have an effect on Hardcore mode as regeneration is disabled. It is mainly used by the gunner in dedicated tank teams, as it is one of a few specializations that carries over to that seat.

Maintenance increases the rate of armor regeneration by 20%.
