Fire Direction Center
this was the name given to the military unit of the Old Republic that was responsible for locating targets and coordinating the pattern of fire for an army's artillery divisions. Each FDC was located, unusually, well behind the front lines, and often in a fortified, below-ground bunker. Here, the sophisticated targeting equipment of the Republic's military was housed and operated, with technicians and commanders on duty around the clock. The FDC was linked directly to the forward artillery units, and provided every piece of artillery with instructions as the battle raged around them. The primary benefit of the FDC is that artillery fire can be coordinates across a large field of battle, bringing the maximum firepower to bear on any given target, depending on the tide of the battle.
