Although the coastal artillery batteries were an economical way to cover large areas of coastline with minimal coverage, they could do little against Commando raids. The task of patrolling the coastline was assigned to the infantry divisions stationed near the coast. These sectors consisted of divisional KVA (Küsten Verteidigung Abschnitt: coast defense sector), further broken down into regimental KVG (Küsten Verteidigung Gruppen), battalion-strength strongpoint groups (Stützpunktgruppe), company-sized StP (Stützpunkt: strongpoints) and finally platoon-sized WN (Wiederstandnest: resistance points). Since the Kriegsmarine received the bulk of the construction work in 1943, these positions were often little more than field entrenchments with a small number of fortified gun pits and personnel shelters. Except on the Pas-de-Calais, there was little fortification of the infantry coastal defenses until 1944. The bunkers and defensive positions were intended to compensate for the severe shortage of troops. German tactical doctrine recommended that an infantry division be allotted no more than 6–10km of front to defend, but the occupation divisions in France were frequently allotted 50 to 100km of coastline to defend, sometimes even more in the remoter locations of Brittany or the Atlantic coast.
