RAID appeared in Caliber with the start of the closed beta test.
The main mission of unit is to avoid casualties. Negotiators and psychologists are the first ones to establish contact with the criminal. Even when the opponent is not eager to compromise, RAID uses non-lethal weapons such as tear gas and smoke grenades.
The development department of RAID has patents on many modern technical devices. Their analogs are used all over the world: communication systems, drones (as well as off-road tracker drones), etc.
