The video this is from is remarkable. He runs up on two tanks, places the grenade under one's turret, runs back to his tunnel, pulls out an RPG, fires that at the other which makes it apparently cook off immediately, and then he jumps back down the tunnel.
edit: And the tunnel is just a hatch in a random bush. Any bush in Gaza could be a fighting hole large enough for anti-tank infantry.
