**Terminal Learning Objective**

Action: Determine the Grid Coordinates of a Point on a Military Map Conditions: Given a standard 1:50,000 scale topographical map, Coordinate Scale and Protractor, pencil and paper Standards: Determine the grid coordinates of a point on a military map by exhibiting comprehension through hands-on demonstration and class participation

3
Military Grid System A network of squares formed by the north- south and east-west grid lines printed on a map. The purpose of the grid system is to enable the map reader to quickly and accurately locate a point on a map.
