Degtyarev DT-29

Pros

 * Rate Of Fire: Decent 600 RPM (RoF) without any modifications
 * Magazine Size: With 63 Rounds within the Drum Magazine, slightly more than the Degtyarev DP-28 or the Maschinengewehr 34.

Between

 * Reload Speed: While not the best Reload Time of 5.70 Seconds, it isn't the worst compared to the Tier 3 Light Machine Guns.
 * Single Fire: Like most of the other Light Machine Guns, the Degtyarev DP-DTM (DT-29) is unable to switch to Single Fire Mode, but you can still tap fire the gun.

Cons

 * Equipment Points: With it only having 7 Equipment Points (8 Equipment Points if taking a Extra Pouch), there's limited space in which you either can go for just the Degtyarev DP-DTM (DT-29) and a Medic Pouch, or a Pistol with a First Aid Kit.
