Ground Laser Target Designator (GLTD) II

The Ground Laser Target Designator (GLTD) II provides ground forces with a compact, lightweight, man-portable laser target designator/rangefinder that is ideally suited for precise delivery of laser guided munitions such as Paveway bombs and Hellfire missiles. Through an RS-422 data link, the GLTD II can be integrated into a digitized, day/night fire control and surveillance system.

Forward Air Controllers (FACs) rely heavily on GPS devices to locate enemy positions and call in fire against targets. For OIF, the 1st Marine Division received 19 Ground Laser Target Designator (GLTD) II systems, which allow the FAC to measure the accurate range to a target and to laze it for LGB employment. In some cases, the systems reached the FAC just hours before crossing the LD. These systems proved invaluable, easy to use, and reliable. The fact that the Marine Corps leased these systems for combat operations validates the requirement for an interim lightweight, durable laser range-finding and designation capability. The system must be fielded in time for units to train with it and in sufficient quantity to equip every FAC or Fire Support Team (FIST). As an incremental step in the acquisition of the Target Locator Designator Handoff System (TLDHS), the Marine Corps should purchase GLTD IIs in quantities to equip all Division air controllers.
