Light Machine Gun

Definition

A machine gun associated with a mobile support role, with varied feed arrangements and cartridge classes. It is not limited to full-power rifle ammunition or one crew size. Exact model, mechanism and configuration require documentation rather than inference from the role label.

Document the actual cartridge, feed arrangement, mechanism and configuration. A support-role label does not require full-power rifle ammunition in every design. Cyclic rate, practical firing rate and a recovered scene sequence also measure different things.
