Notes: This is a blanket designation referring to a family of vehicles that are used for artillery fire control purposes. These vehicles are based upon the MT-LB chassis, with a raised superstructure in the rear of the vehicle. The 1V13 is the deputy battery commander’s vehicle, which is also used as the battery fire direction center (FDC); it has three radios, survey equipment, navigation gear, and fire direction computers. The 1V14 serves as the observation post for the battery commander; it has 3 medium-range and one long-range radios, survey equipment, a laser rangefinder, a 10-meter telescoping long-range antenna, and navigation gear, and night vision gear. The 1V15 is for use by the battalion commander; it has one short-range, two medium range, and two long-range radios, a 10m telescoping long-range antenna, survey equipment, navigation gear, a laser rangefinder, and night vision gear. The 1V16 is the deputy battalion commander’s vehicle that also serves as the battalion FDC; it has three medium-range and two long-range radios, a 10-meter telescoping long-range antenna, meteorological equipment, and a fire direction computer. These vehicles are also known as the ACRV (Artillery Command and Reconnaissance Vehicle), and the chassis is often referred to as the MT-LBu. Each of these vehicles has a machinegun mount by the commander’s hatch.

Notes: The Reostat is a BMD-1 chassis with its turret removed, used as an artillery observation post vehicle. It is used to spot for the SO-120 gun/mortar vehicle. The Reostat is equipped with a mast-mounted ground surveillance/artillery counter-battery radar with a range of 14km, a laser rangefinder/designator with a range 8km, and a computer to coordinate them. The Reostat is also equipped with a land navigation system, and extra radios.

The Spektr is a BMD-1 chassis with its turret removed, used as an artillery fire direction center. It is used in conjunction with the SO-120 gun/mortar vehicle. The Spektr is equipped with extra radios and computers to calculate artillery firing solutions.

Notes: The 1V18 is an artillery observation post version of the standard BTR-60PB. It has a laser designator/rangefinder and an APPK computer system to coordinate the laser rangefinder/designator and the land navigation equipment. The 1V18 has two extra radios, and its turret is a different shape (larger and more squared-off).

The 1V19 is a fire direction center variant of the BTR-60PB. It is equipped with three extra radios and the APPK computer system to compute and calculate artillery and mortar firing solutions. It turret is of the same shape as the 1V18.

Notes: This is a Russian surveillance vehicle normally attached to 122mm and 152mm artillery units. It is based on the BMP-1 chassis, but has a different hatch arrangement to accommodate the different mission. The driver is seated front left with another crewmember seated to his rear. The turret is two-man and fitted with a PKT and various sensors. The PRP-4 has an inertial land navigation system. Computers are fitted for system management and for artillery fire plotting and solutions. The PRP-4 is also equipped with ground surveillance and artillery counterbattery radars. The PRP-4 is normally fitted with at least three long-range and one medium-range radios.
