Final answer:
An officer avoids the threat of a mutiny by changing his strategy and allowing the soldiers to act without restrictions.
Step-by-step explanation:
The primary source mentions a situation where an officer avoids the threat of a mutiny by learning from past mistakes. The officer realizes that it is easier to avoid a large group attack (volley) than a single attack (single shot). Therefore, he changes his strategy by not giving orders that might enrage the soldiers. Instead, he allows them to act on their own without restrictions so that they remain faithful and trustworthy.
