Symmetrical All Wheel Drive: Symmetrical All Wheel Drive (also known as Symmetrical AWD or SAWD) is a full-time four wheel drive system developed by Japanese automobile manufacturer Subaru.  The SAWD system consists of a longitudinally mounted boxer engine coupled to a symmetrical drivetrain with equal length half-axles.  The combination of the symmetrical layout with a flat engine and transmission balanced over the front axle provides optimum weight distribution with a low center of gravity, improving car handling characteristics.  Since 1996, most international market Subaru vehicles include SAWD as standard equipment, with the rear wheel drive BRZ and kei cars as the exceptions.

BILL 1 Anti-tank guided weapon: The RBS 56 BILL is a Swedish manportable SACLOS wire-guided anti-tank missile developed by AB Bofors.  Development began in 1979 and entered production in 1985.

Swingfire: Swingfire was a British wire-guided anti-tank missile developed in the 1960s and produced from 1966 until 1993.  The name refers to its ability to make a rapid turn of up to ninety degrees after firing to bring it onto the line of the sighting mechanism.  This means that the launcher vehicle could be concealed and the operator, using a portable sight, placed at a distance in a more advantageous firing position.

Haflinger (vehicle): The Haflinger is a small, lightweight, four wheel drive, high mobility vehicle about 3.5 m long and 1.5 m wide, powered by a 643 cc flat twin horizontally opposed, rear mounted, air-cooled engine.  Weighing around 600 kg (1322.8 lb), the Haflinger can be lifted by four strong people and yet can carry a load of 500 kg (1102.3 lb).  This truck falls into the category of the light utility vehicle.

Bantam (missile): The Bantam (Bofors ANti-TAnk Missile) or Robot 53 (Rb 53) was a Swedish wire-guided, manual command to line of sight, anti-tank missile developed in the late 1950s by Bofors.  It served with the Swedish and Swiss armies from 1963 and 1967 respectively.  It can either be deployed by a single man carrying a missile and control equipment or from a vehicle.  It has been fitted to the Volvo L3314 and the Scottish Aviation Bulldog.  In the Swiss Army, it was mounted on Steyr-Daimler-Puch Haflinger light wheeled vehicles.

DRDO Anti Tank Missile: The DRDO Anti-tank missile (ATM) is a first generation wire-guided missile developed in India by Defence Research and Development Laboratory (DRDL) of Defence Research and Development Organisation (DRDO).

9M14 Malyutka: The 9M14 Malyutka (Russian: Малютка ; "Little one", NATO reporting name: AT-3 Sagger) is a "manual command to line of sight" (MCLOS) wire-guided anti-tank guided missile (ATGM) system developed in the Soviet Union.  It was the first man-portable anti-tank guided missile of the Soviet Union and is probably the most widely produced ATGM of all time—with Soviet production peaking at 25,000 missiles a year during the 1960s and 1970s.  In addition, copies of the missile have been manufactured under various names by at least five countries.
