Map Reading and Land Navigation
TC 3-25.26 is the Army's map reading and land navigation manual: grids, marginal information, terrain features, azimuths, and navigation techniques. Dated November 2013, it is still the active reference used on land navigation courses and at boards. Note the designator -- it is a TC, not an FM or ATP.
