The Minimi light machine gun was developed by the famous Belgian company FN Herstal, in the late 1970s and early 1980s. Mass production began in 1982 in Belgium, and at about the same time it has been adopted by the US Armed forces as the M249 Squad Automatic Weapon (SAW). Since its introduction Minimi has seen widespread service, and numerous variations have been developed. First, the Para (Paratroop) version came out, with shorter barrel and tubular telescoped butt. This gun traded off some of the range and firepower for compactness and maneuverability. Quite recently, an SPW version was developed, which featured a Para-type buttstock, a barrel of intermediate length (between standard and Para models), and a Picatinny-type rail mount, which allows a wide variety of sights and scopes to be mounted. To save weight, the magazine feed option of the standard and para models has been discarded. This version, in a slightly modified form, was adopted by the US Special Forces Command (US SOCOM) as the Mk.46 model 0 light machine gun.
The FN Minimi has an excellent reputation on reliability and firepower, and the latest reports on failures of M249 SAW weapons in Iraq are attributed to the age of the weapons used – most of the current issue M249 in US Army are more than 10 years old and quite worn out.
The FN Minimi / M249 SAW is an air cooled, gas operated, belt fed, automatic weapon. The Minimi is operated using conventional gas action with the gas piston located below the barrel, and the barrel is locked using the traditional rotary bolt. The barrel is quick-detachable, and has a carrying handle attached to it, to help for quick replacement procedure. The M249 has an alternative feed system, which allows to use disintegrating metallic belts as a primary feed option, or M16-type box magazines as a back-up feed option. The belt is feed using the top feed unit, the magazines are inserted through the magazine port, located at the left side of the receiver and angled down. The Flip-up dust cover closes the magazine port when it is not in use, serving also as a belt guide. When magazine is in place, this cover raises up and closes the belt-way to avoid dual feeds and jams. Since the belt feed uses additional power to pull the belt through the gun, the rate of fire with the belt is somewhat slower (~ 750 rpm) than the rate of fire with magazine feed (~ 1000 rpm). The latest SPW and Mk.46 mod.0 versions of the Minimi have no magazine feed module as a weight-saving measure. The belts are fed from special 200 rounds plastic boxes that can be clipped beneath the receiver. All Minimi versions fire from open bolt to ensure optimal barrel cooling between bursts.
The folding bipod is mounded under the gas chamber, and the gun has provisions for tripod or vehicle mountings. The open sights are standard, with the availability of vide variety of optical and night sights for SPW and Mk.46 versions with Picatinny rails.

By 1985, an intensive research and development program to create a family of what is known to be the Vityaz two-unit CTVs had been completed. This family includes:
? two-unit transport vehicles DT-10, DT-20 and DT-30, with a load-carrying capacity of 10, 20 and 30 tons, respectively;
? two-unit amphibious transporters DT-10P, DT-20P and DT-30P with similar specifications as the regular transporters.
Currently, Vityaz CTVs are in use throughout the whole territory of Russia, as well as in the harsh regions of the Arctic and Antarctica. They are an invaluable part of the transport services for prominent companies such as Gazprom JSC, Rosneftegazstroi, Rosneftegaz JSC, etc. They serve as primary transport vehicles for the personnel who service the extensive oil and gas pipelines throughout Russia, for geologists and scientists who research the dangerous, faraway destinations of Antartica and the Arctic regions. The construction and service industries are also benefiting from the advantages of these vehicles. The DT-30K crane, the DT-30E excavator, refuelling vehicles, mobile workshops, mobile oil refineries, passenger transporters, firefighting vehicles, etc. are mounted on Vityaz chassis. These vehicles are in demand not only in Russia, but throughout the countries of the Middle East and Asia, as well as in North and South America.
Years of operation of these vehicles have proved their reliability and robust design. The vehicle-s design primarily features an unconventional pattern of four active track envelopes providing for large surface contact with the ground for greater stability. In addition to this feature, these ATVs ensures the so called -kinematic method- for turning the articulated tracked vehicle through the -forced folding- of its units. The kinematic method of turn provides a positive tracking force for all tracks during linear movement and while making turns. A combination of the kinematic method of turn and a powerful multifuel engine, along with a hydromechanical transmission, unique track and suspension system with wide band tracks, road wheels with rubber pads, and vertical hydraulic cylinders which allow the two vehicle units to move vertically in relation to each other, make the articulated vehicles with a maximum weight of up to 60 tons more capable in terms of their swamp-, moving sand- loose soil- and snow-going capacity, than any type of single-unit swamp- and snow-going vehicle.
As the two units can be turned relative to each other in the vertical and horizontal planes via hydraulic cylinders or, conversely, can be fixed, the two-unit vehicle can negotiate short (equal to the length of one unit) sections of difficult terrain and such obstacles as ditches and walls and come out of water onto an unprepared bank, ice, or peat.
Owing to their unique design, the Vityaz family of ATVs are capable of operating in conditions impossible for other all-terrain vehicles, for example:
? amphibious return to a mother ship;
? off-road movement with one unit disabled or without one, or even without both tracks of one of the units;
? negotiating ditches and clefts up to 4.0 m wide.
? unloading of a ship offshore if it cannot come close to waterfront (i.e. in the Arctics and Antarctica regions, or in flooded regions, etc.); negotiating waterways in severe ice conditions;
? operation in mountains up to an altitude of 4,000 m.
The DT-10P and DT-30P ATVs are widely used by Russian troops deployed in challenging environmental regions, on islands (for transporting army elements, ammunition, equipment, FOLs and installation of weapon systems). These vehicles are also used by various industries in regions with poor access roads and climatic conditions. They are used to transport various cargoes; deploy digging, forest-working, power, and firefighting equipment; deploy mobile polyclinics and bakeries; transport cranes, excavators, water tanks, etc.; make amphibious unloading of cargoes; tow ships; heave off ships and barges; as well as perform prospecting work on shallow areas of shelf zones.

The 2K22M Tunguska-M1 is a Russian tracked combined surface-to-air gun/missile system. It is designed to provide day and night protection for infantry and tank regiments against low-flying aircraft and helicopters in any weather condition. The complete system is designated 2K22M, with the vehicle designated 2S9M.
The cost of the system is reported to be between 8 and 10 million USD.
