Viper's favourite tank
The forward module contains the driver's cab, main propulsion systems, and most of the Shagohod's weapons. It is a completely autonomous vehicle that can function without the rear module attached, though in this configuration the rocket boosters are lost and the module has no nuclear launch capacity. The main means of propulsion is a pair of augers fixed to runners mounted on hydraulic-actuated arms; at high speeds these are locked in line with the rear and used to pull the Shagohod along, while for low-speed or awkward movements, the arms are brought down diagonally and used to drag the rear section; it is presumably the latter movement mode that gives the Shagohod its name, though the vehicle crawls rather than walking.
The rear module carries the missile launch tube on its right upper surface, with a large fire control radar on the left and the rocket booster units mounted on the sides; the rear sloped surface consists mostly of a large grille, probably the air inlet for the engines and air cushion. Presumably, much of the internal space is taken up by fuel for the boosters and whatever systems are used to produce the air cushion the rear body runs on; it is unknown if it provides any additional support to the front module in terms of fuel or power generation. However, the augers are notably more susceptable to damage when the front module is disconnected from the rear, being immobilised rather than slowed, suggesting the rear module is indeed linked to the forward module's drive systems. The rear module does not appear autonomous; it lacks any visible control station or method of steering.
The Shagohod is armed with two 12.7 mm DShKM heavy machine guns (300 rounds) and one additional turret mount for anti-aircraft work with 360 rounds. In addition, it mounts six 9K112 Kobra Surface-to-air guided missiles, a 100 barrel volley gun, and a single SS-20 "Sabre" IRBM (Intermediate-Range Ballistic Missile).
Complete, the Shagohod weighs 152.5 tons, is 75 feet (22.8 metres) long by 27 feet (8.2 metres) high by 21 feet (6.4 metres) wide, has a maximum road speed (without the rocket engines being activated) of 50 miles per hour (80 kilometres per hour) and a range of 400 miles (650 kilometres). A crew complement of 2 is usual, though one can drive it. Its fuel was unsymmetrical dimethal hyrazine (UDMH), a highly flammable substance that would destroy even the Shagohod if the fuel tanks were still attached.
