USMC Machine Gunnery Practice Test

The purpose of a TandE (traverse and elevation) mechanism on a machine gun mount is to enable horizontal and vertical adjustment of the weapon's aim. This mechanism allows the gunner to accurately target the weapon by making precise adjustments to its orientation. The traverse function permits side-to-side movement, while elevation allows for up-and-down adjustments. This adaptability is crucial in ensuring that the machine gun can effectively engage targets at varying distances and angles, ultimately enhancing the weapon's accuracy and effectiveness in combat situations. Proper use of the TandE mechanism is essential for maneuvering the gun while maintaining stability and control, which directly impacts the success of fire missions.
