SAW - 7.62x39mm Soviet - Russia/CIS - 700 RPM - While long replaced in Soviet arsenals, the RPD has remained a favorite in Asia, Africa, and the Middle East.  Firing from a fixed 100rd belt, the RPD is easier to use from a prone position than the extended (yet smaller capacity) magazines of its replacement, the RPK.  Operators must be careful be maintain short bursts lest the wooden handguards catch fire.  Given that the barrel is not a quick-change type like modern SAWs, a charred handguard is preferable to a melted barrel. D.E. Watters
