Missile-launcher (Derailment)

One of the tank drones locked in on him and began its swift—but unhurried—approach. “All, right, here goes nothing,” he said, and went to hoist himself over the railing. A vice clamped down on his arm—actually a large red clawed hand—and the huge, nearly Builder-scale mech whom it belonged to raised a triple-barreled missile launcher and fired at the drone. The Vehicon was struck center mass and flew back, not so much exploding as disintegrating into a shower of parts as it struck one of the pistons.
