Ian McCollum, a subject matter expert, discusses the concept and future of man-portable chain guns. He explains that while chain guns offer superior reliability, especially in clearing duds, their external power source and associated weight make them impractical for infantry use. McCollum suggests potential applications in unmanned systems where continuous operation is paramount.

Quick Summary

Chain guns are externally powered machine guns using a chain to cycle the action, offering superior reliability in ejecting dud rounds. However, the added weight of their power source makes them impractical for man-portable infantry roles, suggesting future use in unmanned systems like drones.

Frequently Asked Questions

What is a chain gun and how does it differ from other machine guns?

A chain gun is an externally powered machine gun that uses a physical chain, often driven by an electric motor, to cycle the action. This contrasts with traditional machine guns that rely on gas pressure or recoil energy for operation, offering enhanced reliability in ejecting dud rounds.

Why are chain guns not typically used by infantry soldiers?

Chain guns are generally not practical for man-portable infantry roles due to the significant added weight of their external power source, such as motors and batteries. This weight penalty often outweighs the reliability benefits for soldiers who can manually clear malfunctions.

What are the main advantages of chain guns?

The primary advantage of chain guns is their exceptional reliability, particularly in their ability to automatically eject dud rounds without interrupting the firing sequence. This makes them ideal for remote weapon systems where manual intervention is difficult or impossible.

Where might chain guns be used in the future?

Future applications for chain guns are likely to be in unmanned systems. Miniaturized chain guns could be integrated into drones, robotic platforms, or remote sentry systems where their high reliability and automated operation are critical.
