When escorting cargo, for every three trucks there should be an escort vehicle. It can detract attackers attention, go in pursuit. If escort is stopped between two populated areas, the escort vehicle will rush to the nearest militia department. Security company vehicle is more preferable than usual when moving within a city. It's a paradox but a fact that a vehicle with security company logo and name builds up militia confidence, it is not stopped by casual passengers where persons could be very different.
Respectable companies possess armored limousines, cash delivering vehicles.
Pay attention to the fact that all the vehicles should be equipped with portable radios. Inquire whether a company has its office and round the clock duty phone. Try yourself to call the office in non-business hours. Wearing a camouflage by a private guard is prohibited in Moscow. Try to find out how many premises does the company protect and what turnover does it have.
