These items represent the effort of the Germans to sink U.S. landing craft in World War Two at the beaches mainly at Normandy France. And they nearly succeeded except that the tides were in the favor of the Allies. Many of these barricades especially the iron beams were also blown up by the brave U.S. Navy Frogmen of the era. But not enough. This kit is an excellent replica of those barricades and what they were meant to do. I assembled mine by following the directions and although they look off center the completed set are correct. I painted and weathered mine to appear rusted as salt water and air would quickly do this to iron. I placed mine is a completed diorama that suggests action at D-Day landings.
