1.Latrines are so constructed to prevent the contamination of food and water. They are located at least 100 yards (90 meters) downwind (prevailing wind) and down gradient from the unit food service facility and at least 100 feet (30 meters) from any unit ground water source. They should never be placed above gradient of the unit food service facility. For further protection, latrines are not dug to the ground water level or in places where pit contents may drain into the water source. Usually they are built at least 30 yards (30 meters) from the border of the unit area but within a reasonable distance for easy access. A drainage ditch is dug around the edges of the latrine enclosure to keep out rainwater and other surface water. A handwashing device is installed outside each latrine enclosure; these devices should be easy to operate and kept full of water. Each individual must wash his hands after he uses the latrine.
2.When a latrine is filled to within 1 foot (30 centimeters) of the ground surface or when it is to be abandoned, it is closed in the following manner. The pit is filled to the ground surface in 3-inch (8-centimeter) layers; each layer is compacted. This is to prevent fly pupae from hatching and gaining access to the open air. Dirt is then compacted over the pit to form a mound at least 1-foot (30-centimeters) high. A sign is posted with the date and the words �closed latrine,� if the tactical situation permits.
The most important job in the Military is digging a latrine, more important than Strategic and Logistic M.O.S.'s!
The most important man in the field is the lowly private, no one makes a move until his job is done!
