It is the tier three unlock in the Support's first unlock branch; the NetBat Active Camo ID helmet must be unlocked first and the Ganz HMG will be available to unlock after the A12 is. All enemy infantry, light vehicles, or sentry guns within its 90° sight cone will be targeted. However, it can barely tilt its gun in the vertical axis, and can only focus on one target at the time. The A12 Enforcer will fire at visible targets out to medium ranges, but is most effective against targets within 50 meters. Past this, it will do lower damage and have significant spread. This makes the sentry well suited for area denial in narrow areas, like alleyways or corridors. It can be particularly effective at defending the reactor corridors on-board Titans, due to their cramped and narrow nature.
