Name one advantage of a two-man fighting hole.

A two-man fighting hole offers the clear advantage of allowing one individual to rest while the other maintains watch or engages in combat as necessary. This division of labor helps sustain the effectiveness of the fighting position over time. Given the demands of combat situations, having the ability to rotate tasks can significantly enhance endurance and operational capability.

When one Marine is able to rest, they can recover strength and maintain higher levels of alertness, which is critical during extended engagements. This ensures that the fighting hole is continuously manned and ready for any threats while also allowing for the individual preparing for a shift to be more mentally and physically prepared.

While other factors such as improved camouflage, increased firepower, or enhanced communication can play roles in combat effectiveness, they do not directly speak to the operational sustainability and personal well-being that resting supports.
