St George ripping off Cerberus’ head

St. George limped over to the fallen titan. It was like a wounded turtle, stuck on its back with no limbs left to push itself over. The stump pounded on the ground. The handless arm swung at him again but couldn’t reach him. Billie, Ilya, and the others approached from the north, reloading as they closed in.
St. George hooked his fingers under the helmet’s chin. He braced his foot against the armored shoulders and pulled.
The battlesuit groaned, metal squealed, and Cerberus’s armored skull ripped free of the body. Shrapnel sprayed like blood. A tangle of cables dragged loose from the armored collar. Each one snapped, sparked, and popped apart. The thrashing limbs went limp.
