Bends of the enveloping guide of the stock, which face each other, are equipped with upper longitudinal ribs with possibility of enveloping the bends. Elements facing downwards and arranged on lateral sides of the metal base of the firing unit prevent movement to sides of bends of the enveloping guide of the gun stock. On lower surface of the enveloping guide stock from the nose piece of the back plate and to the muzzle part, which envelopes from below the guide stock of a cross piece, there arranged are two strengthening longitudinal stiffeners forming side walls of a collar of a lower longitudinal window in the middle part of the stock for lower sleeve ejection. In the muzzle part of the stock there formed are side connection elements for arrangement under the fore-end of "bayonet-knife" attachment elements or an under-barrel-mounted grenade dispenser, which are attached onto the guide gun stock.
	Thermal target simulator Invention can be used to perform flight development tests of jet projectiles (JP) equipped with cassette payloads (CP) with self-sighting submissiles (SSS), which operate in infrared (IR) ranges, as well as other types of ammunitions equipped with infrared target-seeking heads for simulation of thermal emissions of military objects at dislocation points or in source areas. The essence of the invention consists in the fact that a thermal target simulator includes a fabric cloth and heaters. Fabric cloth is made in the form of a cover and arranged on a demountable frame including two side walls and two end walls. Rear end wall is equipped with a metal shield, and the cover is equipped with a skirt located along the perimeter of the frame; with that, the cover and the skirt are made from fabric material, for example laminated cloth (GOST 7297-90), dyeing shade is dark (GOST 29222-91). Heaters are located inside the frame on supports adjustable as to height in compliance with thermal parameters of the simulated target; the cover is fixed from above on the frame by means of longitudinal clamps. The skirt adjacent to the rear end wall is fixed from below by means of a transverse clamp. Clamps are equipped with elastic fasteners, and the device itself is equipped with a simulator of the outline of the horizontal target projection, which is made in the form of stiff reference points connected with flexible connections.
	Non-discrete passive sighting equipment Non-discrete passive sighting equipment relates to sighting devices for arms and is characterised by a pair of lines located opposite each other relative to a vertical plane and having such curvature, considering derivation correction, that angular distance between them as to horizontal plane at the depth of any sighting angle is equal to angular width of a stationary target at firing distance for that sighting angle. The equipment is used as a part of a structure having an optical axis. Without using any active (emitting) ranging means it gives to the arms such a sighting angle throughout the length of sighting distance, which accurately corresponds to distance to the stationary target. Therefore, maximum probability of target penetration throughout depth of sighting distance is provided.
	Device for control over combat tracked vehicle optimum operating conditions Proposed device consists of data converter unit (1) and data transmitter unit (2). Data converter unit (1) consists of ADC of electric signals from engine cooling fluid temperature control transducer, engine oil temperature and pressure transducer (3), ADC of electric signals from engine crankshaft rpm transducer and vehicle speed transducer (4), data synchronisation and storage unit (5). Said data synchronisation and storage unit (5), consists of microcomputer (6), timer (7), memory unit (8) and standby power supply (9). Data transfer unit (2) consists of microprocessor (10) radio module (11).
	Bullpup small arms Bullpup small arms of an automatic weapon with a bayonet with preliminary roll-out of a fighting unit include a metal longitudinal base. Also, there are sleeves enclosing a gun barrel that is equipped with a right side gas branch pipe. There is an upper thrust vertical rib in the muzzle part of an under-barrel cantilever element for a spring shock absorber of recoil of the fighting unit. Gun barrel sleeves are of a composite type with possibility of weld joints of lower halves of sleeves with the under-barrel cantilever element. A breech composite sleeve of the barrel is arranged between a cartridge chamber caught with a cylindrical sleeve having locking lugs for the bolt, and an annular thrust collar of the barrel, which is arranged in front and prevents longitudinal displacement of the gun barrel. There is also a left side bracket on lower half of the composite breech sleeve of the barrel, which is longitudinal to the cartridge chamber, and having a semi-axis in its breech part serving as an element of the feeding device of ammunitions of these arms. Besides, the muzzle composite sleeve of the barrel is arranged in front of an eye lug of the right gas branch pipe having a T-shape in a horizontal projection of the barrel and a weld joint of its breech branch with the lower half of the breech composite sleeve of the barrel.
