This is actually covered in the Finnish article pretty well. The laws governing the use of military equipment are pretty strict, and actually the personnel in KARHU are not allowed to use military equipment. This equipment means basicly anything bigger than standard personal weaponry. All other equipment must be used by DEFENCE FORCE STAFF (not conscripts). Also, the use of these things requires ministry of interior to make a request of their use to defence ministry. But these are VERY VERY extreme cases, and the laws only exist as precaution. The usual case of requesting armored vehicles for protection rarely involves KARHU, and they are usually not used near shooting, but more as a backup (since the crews are conscripts and law forbids the use of conscripts in situations, where they might get shot or injured otherwise).
