The RM-38 was a Soviet 50 mm light infantry mortar, developed as a variant of the M1938 120 mm mortar. The barrel was clamped at two elevation angles only - 45 and 75 degrees. Range variations were made by altering a sleeve round the base of the barrel. This sleeve opened a series of gas ports which bled off exhaust gases and so determined the range.

The project was deemed overly complex and expensive, and was only produced for a short time, before being replaced by the Model 1939. Despite the small number produced, some fell into German hands in 1941, who introduced them as the 5 cm Granatwerfer 205/1(r).

The RM-38 or 50-RM 38 (50-mm company mortar model 1938) was based on the Stokes mortar. It was further developed as the RM-39 and RM40.

The Red Army of the USSR divided mortars into company (RM) battalion (BM) and regimental (HM) mortars. Development of a light 50mm company mortar started in 1937. The RM-38 was approved for use in 1938 and entered production in 1939. In the space of just over a year RM-39, RM-40 and RM-41 replaced each other in succession. RM-41 remained in production until 1943, when the USSR decided to cease making 50mm mortars. Only RM-41 was new design the others being incremental improvements of the original RM-38.

This model saw widespread use by the USSR in World War II. Captured in large numbers they were also re-used by the Finns and Germans. After World War II the USSR supplied them to North Korea and Vietnam.
