The stacks of aircraft serving as fire-support weapons for soldiers and Marines in Iraq were controlled by two organizations: the air support operations center (ASOC), in the Army area of operations; and the
direct air support center (DASC), in the Marine area of operations.
VMGR-152's secondary missions include rapid ground refueling of aircraft and motorized vehicles, aerial transport and delivery, airborne
direct air support center, and battlefield illumination.
CAC2S will provide a common set of hardware and software that will replace the Marine Corps' current Tactical Air Command Center, Tactical Air Operations Center,
Direct Air Support Center, Low Altitude Air Defense Battalion, and Marine Air Traffic Control System functions.
