 Allied intelligence had identified the coastal defenders as a reinforced battalion (800 – 1000 men) of the 716th Infantry Division. This was a static defensive division estimated to comprise up to 50 % of non-German troops, mostly Russian volunteers and German Volksdeutsche. The recently activated but capable 352nd Infantry Division was believed to be 30 kilometres (19 mi) inland at Saint-Lô and was regarded as the most likely force to be committed to a counter-attack. As part of Rommel's strategy to concentrate defenses at the water's edge, the 352nd had been ordered forward in March, taking over responsibility for the defense of the portion of the Normandy coast in which Omaha was located. As part of this reorganization, the 352nd also took under its command two battalions of the 726th Grenadier Regiment (part of the 716th Static Infantry Division) as well as the 439th Ost-Battalion, which had been attached to the 726th. Omaha Beach fell mostly within 'Coast Defense Sector 2', which stretched westward from Colleville and allocated to the 916th Grenadier Regiment, with the third battalion 726th Grenadier Regiment attached. Two companies of the 726th manned strongpoints in the Vierville area while two companies of the 916th occupied the St. Laurent area strongpoints in the center of Omaha. These positions were supported by the artillery of the first and fourth battalions of the 352nd Artillery Regiment (twelve 105 mm and four 150 mm howitzers respectively). The two remaining companies of the 916th formed a reserve at Formigny, two miles (3 km) inland. East of Colleville, 'Coast Defense Sector 3' was the responsibility of the remainder of the 726th Grenadier Regiment. Two companies were deployed at the coast, one in the most easterly series of strongpoints, with artillery support provided by the third battalion of the 352nd Artillery Regiment. The area reserve, comprising the two battalions of the 915th Grenadier Regiment and known as'Kampfgruppe Meyer', was located south-east of Bayeux outside the immediate Omaha area.
