エバン・エマール要塞
The perimeter blockhouses are each armed with two machine guns. Infantry for exterior protection were further armed with 24, and 47mm anti-tank weapons, two 81mm mortars, four machine guns and eight automatic rifles. These were added in 1941, along with barbed-wire entanglements, stated to be lessons learned from the successful German assault on the Belgian Fort Eben-Emael.
