What mechanism does the RPD use to feed ammunition?

The RPD (Ruchnoy Pulemyot Degtyaryova) uses a belt feed system to supply ammunition. This is a key feature of many machine guns and light machine guns, allowing for continuous firing without the need to reload frequently. The belt feed system consists of linked metal or fabric belts that hold the cartridges together, enabling a steady and reliable feed into the chamber of the weapon as it is cycled through its firing mechanism.

This continuous feed capability is particularly advantageous in sustaining fire during extended engagements, making it effective for infantry support roles. The design of the belt also helps reduce the chances of jams that can occur with other systems that require manual reloading or switching of magazines. Understanding the functioning of the RPD's belt feed mechanism is crucial for effective operation and maintenance of the weapon in various combat scenarios.
