Establish tactical-wire entanglements parallel to and along the friendly side of the final protective line. Use them to breakup enemy attack formations and to hold the enemy in areas covered by the most intense defensive fire. Extend tactical entanglements across the entire front of a position, but you need not make them continuous.
