The PT-76 was used as the standard reconnaissance tank of the Soviet Union and Warsaw Pact armies. It was also intended for water obstacle fording operations and naval infantry landings. It served in the reconnaissance subunits of tank divisions and mechanized divisions of the Red Army and Soviet marines divisions. Although it has been replaced in front line service by the BMP-1, it may still be found in the reconnaissance companies and battalions of some motorized rifle and tank regiments and divisions, as well as in naval infantry units. Aside from its reconnaissance role, it is also used for crossing water obstacles in the first wave of an attack and for artillery support during the establishment of a beachhead. The main disadvantage of the BMP-1 and the BRM-1 when compared to the PT-76 is the absence of a powerful main armament. However, the BRM-1 is fitted with more modern reconnaissance equipment. Also, both vehicles have stronger front armor and superior mobility features and the BMP-1 can carry up to 8 fully equipped soldiers inside. The PT-76 is still on active service in a number of countries mainly in the third world. The Russian Army is reported to have used PT-76 units in the ongoing war in Chechnya.
