The 9P149 is a tank destroyer of Soviet origin. It was developed to supplement the BRDM-2 based tank destroyers in Soviet service. A more capable tank destroyer was desired with the advent of new Western tank such as the M1 Abrams and Leopard 2. The 9P149 uses the same 9M114 Shturm anti-tank missiles as used on the Mi-24 attack helicopter.
The 9P149 is based on the chassis of the MT-LB tracked armored personnel carrier. The troop compartment is occupied by a single round retractable pedestal launcher that is connected to an automatic loader. Instead of the small machine gun turret a large optical tracker is fitted. Only early model Shturm missiles can be launched since the improved models are too long for the automatic loader in the 9P149. With the launcher retracted the 9P149 looks very similar to the MT-LB and can be identified by the optical tracked instead of the small one man turret.
