In machine gun tactics, what term describes a space where line of sight is compromised?

The term that describes a space where line of sight is compromised is dead space. This refers to areas on the battlefield where direct fire cannot effectively reach due to obstacles or terrain features that block the line of sight. Dead space can occur in various situations, such as behind mounds, in depressions, or around structures, where the weapon’s firing angles do not allow for effective targeting of an enemy.

Understanding dead space is crucial for machine gun employment because it helps determine the best positioning of the machine guns and the need for additional support or flanking maneuvers to cover those areas. Identifying these spaces allows for better tactical planning and ensures that all vulnerable areas are accounted for, enhancing overall effectiveness in combat scenarios. This knowledge assists gunners and crew in coordinating fire support and identifying when to employ tactics such as creating crossfire or using indirect fire to cover dead spaces.
