 The next exercise is to get one man over a tall electric fence in half an hour using only equipment provided to them (mostly wooden planks and oil drums).Jones inevitably volunteers to be the man over the fence, and tries to get Walker to catapult him over the fence, but in doing so they break the only decent long length of wood, thus dooming all other attempts to failure.After half an hour the platoon still have not done it, so they plead for more time.
