From the website:
The 9P148 Konkurs (Contest, or Spandrel as its missile is designated by NATO) is a light mobile armoured vehicle mounting five excellent wire-guided 9M113 Konkurs (AT-5 Spandrel) anti-tank missiles. The 9P148 vehicle is based on the same vehicle used in the reconnaissance role as the BRDM-2. It has good cross-country and road speed allowing it to get into good positions from which to launch its missiles. The roof mounted launch system meant that the vehicle could hide its bulk, only exposing the launcher and gunner’s sight on the top of the roof to the enemy making it difficult to kill or suppress should the enemy even see the weapon firing.
