What is the function of a tactical flashlight mounted on a machine gun?

A tactical flashlight mounted on a machine gun primarily serves to improve visibility during low-light conditions. In environments where natural light is limited or absent, being able to see the target clearly is crucial for effective engagement and decision-making. The use of a tactical flashlight allows operators to identify targets and ensure proper alignment with the weapon, enhancing overall situational awareness and safety.

While there are other potential uses of a tactical flashlight, such as signaling, the main function in this context is to provide illumination that aids in target acquisition and threat recognition during night operations or in dimly lit environments. This capability is essential for maintaining the operational effectiveness of the weapon and the safety of the crew using it.
