III号突撃砲
An extensive network of coastal artillery batteries with heavy (&gt;15.5 cm), medium (12-15.5 cm) and light (&lt;12 cm) ordnance was set up around the entire coast. These were typically placed so as to cover the approaches to main population centres and likely landing sites. The batteries were also generously equipped with close combat weapons, such as machine guns and small arms. By the end of the war, there were 221 batteries along the coast, under either "Kriegsmarine" or "Heer" command. There were also anti-aircraft artillery ("Marine Flak") batteries in Kristiansand, Bergen, Trondheim, Bogen, and Harstad; these were armed with 88-mm pieces. The tanks available for the German defense were "Panzer III"s (50 mm L60 and 75 mm L24) and "Sturmgeschütz III"s (75 mm L48).
