How deep should the walls of a fighting position be to the shooting platform?

The correct answer indicates that the walls of a fighting position should have a thickness of 4-6 inches to the shooting platform. This measurement is essential for ensuring adequate protection and cover for the crew operating the machine gun.

Having walls in this thickness range allows for effective deflection of incoming fire while still maintaining enough structural integrity to support the position. Too thin of walls, such as those less than 4 inches, may not provide the required protection in combat situations, potentially putting personnel at risk. Conversely, walls thicker than 6 inches could impede mobility and make it more challenging for crew members to operate effectively, especially when quick repositioning is necessary during engagements.

Overall, a wall thickness of 4-6 inches balances the need for protection with functionality, which is critical in combat environments where both survivability and operational capability are paramount.
