Wooden ramps were used by the Germans in World War II to defend areas from terrestrial and aquatic/semi-aquatic vehicles. A wooden ramp consisted of a medium-sized tree trunk angled 15-20 degrees with the raised end towards land and supported by two or four legs. The wooden ramp could flip an amphibious vehicle over as it landed on the beach. The devices were sometimes made additionally dangerous by attaching mines to the log.
