Skill

He was not a gifted engineer; his hands were not built for detail work. But he had educated himself on every weapons system used by Decepticons or any enemy they had ever encountered, and none here were unfamiliar. Rather than waste time attempting to clean crevices that his fingers could not easily reach, he disassembled all the weapons to bare components, blasted them clean with the sonic washer, and reassembled them. There was a small target gallery set up in the room: he fired each one twice, adjusted the balance and aim, and then confirmed with one final shot that he was able to hit the precise center of each target without compensating for the weapon: his preferred balance between testing and energy expenditure.
