How is "concealment" different from "cover" regarding machine gun employment?

The distinction between "concealment" and "cover" is critical in machine gun employment, as it affects how personnel and equipment are positioned for both offense and defense. Concealment is primarily concerned with preventing detection by the enemy, allowing a machine gun team to remain hidden while preparing for engagement or movement without being spotted. This aspect of concealment supports the element of surprise and enhances tactical advantage.

On the other hand, cover refers to physical protection from enemy fire. It provides a barrier that can shield personnel or equipment from bullets or shrapnel, allowing them to operate more safely in combat situations. While cover is vital for survivability, it does not necessarily obscure the gunner's or the team’s position from enemy observation.

Thus, the correct answer highlights that concealment prevents detection, allowing for stealth and surprise, while cover offers protection from incoming fire, crucial for sustaining operations and maintaining the ability to engage effectively.
