Explosively formed penetrator improvised explosive device

This Hamas-linked explosively formed penetrator improvised explosive device is a locally made anti-armor charge built around a concave copper liner. During the Israel-Hamas War, IDF seizures in Gaza and press briefings tied Shawaz EFP variants to Hamas's armored-vehicle threat and October 7 attack kits.
