Explanation: At the Battle of Cynoscephalae, a Roman tribune, a mid-level officer, demonstrated the flexibility and responsiveness of the Roman military system by wheeling around some 2,500 men, pursuing fleeing skirmishers, to hit the rear of the opposing Macedonian phalanx, which had fought the other part of the Roman force to a standstill. As the Macedonians could not effectively turn their formation of long pikes, they were utterly overrun, turning what seemed to be a hard-fought draw or near-win for the Romans into a total and devastating victory.
