H-158. Tanglefoot is used where concealment is essential and to prevent the enemy from crawling between fences and in front of emplacements. (See figure H-25, page H-52.) The obstacle should be employed in a minimum width of 32 feet. The pickets should be placed at irregular intervals of 2 ½ feet to 10 feet. The height of the barbed wire should vary between 9 to 30 inches. Tanglefoot should be sited in scrub, if possible, using bushes as supports for part of the wire. On open ground, short pickets should be used.
