FN Herstal, a world leader in small arms manufacture, has launched the FN Fire Control Unit (FN FCU). Successful target engagement with 40mm LV tubelaunched grenades requires precise range estimation to the target and launch at the exact elevation angle, while keeping correct azimuth aiming. With FN FCU, the shooter can now rely on a light, compact and easily used device to significantly maximise first-round hit probability.

The FN FCU consists of: a laser range finder (LRF), which calculates the distance between the shooter and the target; a clinometer, which measures the difference in elevation/depression between the target and the shooter; a ballistic computer, which calculates the angle of launch required; a moving red reticle sight, which gives the correct aiming point; and a weapon cant indicator, which indicates when weapon realignment is required.
