Square cabin first appeared in the United States in the 1950s. Due to the combat function equipment, all kinds of maintenance equipment, medical equipment, cooking equipment and so on have been installed and debugged in the square cabin, so it has a considerable carrying capacity, combat response time is short. Square cabin sealed performance is good, with climate protection ability and battlefield threat protection ability, can give cabin functional equipment, personnel to provide suitable working and living environment.
Because the square cabin is suitable for command and control systems, test systems, communication systems, technical support equipment, field medical facilities and various types of medical equipment loaded carrier and personnel workshop, so to the late 1960s and early 1970s, the United States, Britain, France, Germany, Italy and other developed countries have recognized the significance of the square cabin, a large number of research and development production and equipment.
The modernized missile force command square cabin is actually a mobile command post with complete functions. Of course, the above functions are sometimes dependent on multiple square cabin vehicle intelligence, fire and communications and other security units to achieve. For example, the Russian P-145BM command vehicle is equipped with a GLONASS global satellite navigation system and cameras, capable of transmitting the commander's instructions and real-time images of the battlefield and other aspects of intelligence information.
The Command Vehicle ensures the processing of intelligence information required for command and control of tactical links between marches and stops, and can be used as a stand-alone command post or as an integral part of a communications and command hub, which can maintain communications with four users at the same time, with a short-wave range of 350 kilometers and an ultra-short-wave range of 50 kilometers.
The square cabin adopts a high load-bearing chassis, but also after the appearance of deformation camouflage, special painting, the use of non-metallic materials to improve visible light, infrared and electromagnetic low detectability, the main body has been reinforced, the doors and windows have been sealed, and its own power supply and air-conditioning, all the air inlets and outlets must be equipped with a three-proof filtration function, the square cabin itself and the internal equipment have been through the electromagnetic shielding design.
In the case of meeting the above requirements, but also need to provide enough space and ergonomic considerations as far as possible, will not make people work for a long time feel depressed and fatigue. For example, the Russian 9K58 brigade and battalion command vehicles, in addition to command equipment, are equipped with air conditioners, ventilation and filtration equipment, heating equipment, primary sterilization devices, chemical and radiation reconnaissance equipment.
