The 9P149 is a tank destroyer of Soviet origin and in this example, it is a vehicle carrying radio guided anti-tank system designated 9K114 Shturm which uses the 9M114 Kokon (Cocoon) missile. Same missile as used by the Mi-24 helicopter.
The kit comes in standard gray plastic in 15 gray sprues, two clear sprues, decals and 2 photoetch frets. Total is 790 parts many of which are very tiny as the entire vehicle is a about a scale foot long. There is an entire interior which covers the driver compartment, engine and transmission. You will decide how far you want to build the interior if you don’t decide to open the hatches. The interior is really nice but I didn’t find many references no color call outs on the instructions.
