2nd Bn, 56th Arty, 1966-68 (Source: Richard Tracy) The IFC lightning rods are prominent -- sticking up from the camo net canopy. Beyond them is the LOPAR: known simply as the "Acq" (pronounced "ack"), it supplied general radar surveillance video -- displayed on BCT and RCT consoles -- to the IFC. The MTR, at right, was computer-controlled: it tracked the missile, and sent guidance and burst commands to it. In the foreground are the BOC generator shed, gasoline and diesel fuel tanks, lightning rod, and (as yet unoccupied) radar tower.
