DTM: The Soviet Tank Version of the DP-27 LMG

Published on February 8, 2020
Duration: 11:22

The DTM is a specialized tank variant of the Soviet DP-27 LMG, featuring design changes like relocating the recoil spring to prevent heat failures. While it retains a high rate of fire, its tall bipod and short sight radius negatively impact accuracy compared to the infantry DP-27. The collapsible stock and removable bipod/sight assembly are key for tank integration, but the serrated stock is noted as uncomfortable.

Quick Summary

The DTM is the tank-specific variant of the Soviet DP-27 LMG, featuring a relocated recoil spring for better heat management in vehicles. It includes a collapsible stock and removable bipod/sight for tank integration, though its tall mount and short sight radius reduce dismounted accuracy.

Frequently Asked Questions

What is the main difference between the DTM and the standard DP-27?

The DTM is the tank-specific variant of the DP-27. Its primary design change moved the recoil spring to the rear of the receiver to prevent heat-related failures common in confined tank spaces, unlike the DP-27's under-barrel spring.

How does the DTM's design facilitate its use in tanks like the T-34?

The DTM features a collapsible metal stock and a removable bipod and front sight assembly. These allow the gun to fit into the ball mounts of Soviet tanks and be stored compactly, while retaining zero when reattached.

What are the accuracy limitations of the DTM when used dismounted?

The DTM's accuracy is hampered by its tall bipod mount and short sight radius, which are optimized for tank use. This configuration makes it less accurate for infantry dismounted use compared to the standard DP-27.

What is the magazine capacity of the DTM and how is it loaded?

The DTM uses a distinctive 60-round drum magazine, which is taller and narrower than the standard DP-27's 47-round drum. Loading it is a tedious manual process involving tensioning an internal spring.
