Wheelchair, barracks and a bakery
What is the use of good weapons when a soldier has a stomach empty and can no longer press the trigger? For this reason, outdoor fire was used for a long time, and big military trolleys probably do not surprise anyone. But under windy conditions, food with sand and dusters often had to be towed under the tooth.
The hangings were erected and the caterpillars were erected, but it would have been more convenient to put the wheels on the canteen. Designed-Made! This is how the car canteen or canteen (15T117) was created, which was designed for a comfortable catering for rocket and artillery outdoor activities.
In the front of the MAZ-543M chassis, there was a four-seater sleeping bag, or a coupe-serving staff. One can dine at the dining room, watch TV and listen to the radio of 16 military personnel. For cleanliness, the kitchen section even had a shower room for the staff. Of course, there were no fridges and other necessary kitchen appliances. The food supply was 750 kg and drinking water was tanks of 2,200 liters.
But when the abdomen was full, it was necessary to spend some time overnight. If already the canteen's wheels were down, why can not they do it with a barracks? Ready car-dormitory, also called dormitory caravan (15T118). The moving barracks had two entrances, and the military hotel was luxuriously outdoors - equipped with air conditioning, clothes and boot drying cabin, an efficient ventilation and heating system. There were six separate booths in the dormitory, which included the lower communes and cabinets for things.
In addition, there were retractable upper sleeping areas, seating, chairs, mirror closet, window, luminaire, fan, radio and thermometer. Depending on whether two or four people were fitted in the "room", 12 to 24 military personnel were fitted on wheels with personal weapons and things. In the latter variants there was a shower cabin. It is worth noting using the MAZ-543 series, a number of other exciting machines were built.
For example, a hospital hospital, a power plant, powerful aerodrome fire fighting machines, and various rocket guards, communication, fire control and locksmiths. The production of the MAZ-543 chassis went through the collapse of the Soviet Union, but small-scale orders lasted until the middle of the first decade of the year 2000.
By this time, nearly 11,000 543-Series machines were manufactured, the successor of which was the quad-core 22-tonne MAZ-7930.
