What is the minimum number of persons required to safely operate a crew-served weapon?

The minimum number of persons required to safely operate a crew-served weapon is two personnel, consisting of a gunner and an assistant gunner. The gunner is responsible for firing the weapon, while the assistant gunner assists with ammunition supply, weapon loading, and maintenance, as well as providing immediate support during operations. This division of responsibilities is crucial for operational efficiency and safety. Having two personnel ensures that the crew-served weapon can be operated effectively, with one individual focusing on aiming and firing while the other manages logistics and addresses any issues that may arise.

In this context, having fewer than two personnel compromises the weapon's operational capability and safety. While more personnel, such as additional gunners or support roles, can enhance the effectiveness and response capabilities of the crew, they exceed the minimum requirement for safe operation. Thus, two personnel provide the essential balance of firepower and support, making this the correct answer.
