This video is great, but the version used by Moscow's OMOH is GAZ-233034 SPM-1. This version has 2 hatches instead of only one with guns'ring. From Wikipedia "Special police car GAZ-233034 SPM-1 is intended for use as a vehicle and operating-company car Russian Interior Ministry in counter-terrorism operations, the tasks of territorial defense, assisting FPS Russia, including the transportation of personnel at the march, to protect the crew from fire weapons and explosive devices damaging factors.
GAZ-233034 SPM-1 is an armored car, a third class of ballistic protection to IEC 50963-96 side and aft projections. In the frontal projection machine is protected by a class 5 Standard. In the roof of the car two rectangular hatch without bindings under heavy small arms. Firing of personal weapons crew and troops on early models through closing loopholes in the form of large valves in the body and doors. In the later versions - through the opening armored glass in the doors and on the sides of the car. In the cabin air space for the driver, older cars and 7 people landing. On the roof of the car can be set remotely controlled setting shooting special means to disperse demonstrations, "Gun carriage." Provides space for the radio station and the radio-controlled explosive devices blocker". Although I think the OMOH use Meng's version. I'm seeking in my Tigr's folder and if I find I'll post it.
