An analysis of battlefield videos released by Hamas and interviews with three Hamas members and scores of Israeli soldiers

Using civilian homes and infrastructure — including medical facilities, U.N. offices and mosques — to conceal fighters, tunnel entrances, booby-traps and ammunition stores;
Ambushing Israeli soldiers with small groups of fighters dressed as civilians, as well as using civilians, including children, to act as lookouts;

The video seems to show Hamas fighters, their faces blurred, sitting on patterned mats as they plan the attack. They use pen, paper and a digital tablet to draw simplistic maps detailing where they want to plant a set of roadside mines.
“We ask, O Lord, for the ambush to achieve its goals — let us kill your enemies, the Jews,” the narrator says.
