Field manual 5-15 describes field fortification methods and gives details of construction of entrenchments, emplacements and shelters.
It also outlines the principles of terrain appreciation which apply to field fortifications, and explains how to combine individual field fortifications into a unified system by means of organization of the ground. It does not cover the subject of obstacles, which is treated in FM 5-30.
