The aircraft carrier
There is a pretty large lip on the side of the bridge of the small boat that is shielded from the carrier. You maneuver your robot behind it as the turret prepares another shot, letting it loose into the bridge, the bullet rips through both sides of the multi-layered steel and you feel a dull thud as it nudges your robot, by this point it is not powerful enough to actually hurt your robot, but definitely leaves a dent. You quickly assess your robot's damage and find your whole chest area is badly scratched but not pierced, along with your left arm. Your shield has a small hole in the bottom that is definitely worth considering
