What should be avoided to ensure safety during machine gun operations?

To ensure safety during machine gun operations, it is essential to avoid overhead obstacles. Overhead obstacles can pose significant risks as they may obstruct the line of fire or deflect rounds, potentially causing unintended injuries to personnel or damage to equipment. These obstacles can interfere with the proper functioning of the weapon system and affect the overall effectiveness of the operation.

Additionally, when engaging targets, it is crucial for gunners to have a clear and unobstructed field of fire, which overhead obstacles can compromise. Ensuring that the area is free from such hazards allows the crew to operate more effectively while minimizing the risk of accidents or unintended consequences during firing. By maintaining a safe environment free from distractions and dangers, the effectiveness of machine gun operations is maximized.
