Description


Introduction

The RGO-78 is a defensive hand grenade of Soviet origin. It was developed in the 1970's. Externally it looks very similar to the RGD-5, on which the design was based.

Design

The RGO-78 is a dedicated defensive version of the RGD-5. It contains less explosive and has a much thicker pre-fragmented steel body. The steel body contains about 850 steel balls.

Firepower

The RGO-78 has a casualty radius of about 20 meters. Although it can be thrown further than the casualty radius, the operator must seek cover. Otherwise, some fragments may reach the operator.

Users

The RGO-78 was adopted by Soviet forces. It is also exported to other nations, mostly in the Warsaw Pact and other nations with ties with USSR. Although common, the RGO-78 is not nearly as prolific as the earlier RGD-5.

Variants

RGO-78
A single live version of the RGO-78 exists. The more compact DVM-78 time delay fuse was developed for this grenade, although it can in theory be fitted with the older UZRGM fuze.
RGO-1M
Practice grenade with similar weight, size, flash and noise. Does not produce any harmful effects.
