Affectionately referred to as the "70km sniper round", the GMLRS Unitary has a 200lb High Explosive (HE) warhead for attacking point targets with reduced collateral damage by providing a "one round, one kill capability". GMLRS unitary is the Army's only surface-fired, precision, longer-range indirect fire munition available to troops in contact in an urban environment. GMLRS is a precision munition providing increased range to 70KM, and Global Positioning System (GPS) accuracy. GMLRS unitary has three fuze settings for use against personnel in the open (proximity fuze); lightly fortified bunkers (delayed fuze); or a single, lightly armored target (point detonating fuze). The new Tri-mode fuze allows airburst, point impact and delay modes forpenetrator capability. Proximity sensor firing mode is selectable for 3 Meter & 10 Meter height of burst [HOB] at approach velocities near Mach 2.5.
