The Wiesel was developed for the West German army to meet a requirement for an air-transportable light armored vehicle for use by its airborne troops, as the infantry of the West German Bundeswehr, especially airborne infantry, were considered unprepared to successfully fight enemy main battle tanks (MBT) in the 1970s. The requirements were that the vehicle should fit in common NATO transport planes and could eventually be air-dropped. It should be able to fight infantry as well as enemy tanks or aircraft. Porsche produced some prototypes of the future fighting vehicle for the Bundeswehr in 1975, but the Bundeswehr stopped the project in 1978 due to lack of funds. Nevertheless, Porsche continued development, because of interest from other countries.
The Bundeswehr eventually ordered 343 of the vehicles in 1985.[1] The Wiesel was introduced as a new weapon system for the Bundeswehr with deliveries beginning in the late 1980s. The vehicle was named Wiesel ("weasel") because of its small size and agility, which make it very difficult to detect on the battlefield. Production of the Wiesel 1 ended in 1993. Of 343 Wiesel 1 vehicles, 210 were armed with Raytheon TOWwire-guidedanti-tank guided missile system and 133 have the one-man KUKA turret E6-II-A1 armed with the dual-feed Rheinmetall Mk 20 RH-202 20 mm autocannon. Germany deployed both types to Somalia in 1993 as part of the United Nations forces intervention in the Somali Civil War (UNISOM II).
The Wiesel 2 is an enlarged and extended version of the Wiesel 1 with five road wheels instead of four, and a more powerful engine. The Bundeswehr ordered 178 of the new vehicle in various types, including air defense, radar, and anti-aircraft missile launcher, 120 mm mortar carrier, command and fire control, and ambulance variants.[1] The Wiesel 2 entered service in 2001.

Depending on the exact configuration, the Wiesel 1's length is about 3.55 metres (11.6 ft), height 1.82 metres (6.0 ft), and width 1.82 metres (6.0 ft). At only 2.75 metric tons (3.03 short tons), it weighs less than the armored variant of the U.S. Humvee military light truck. The engine is a 64 kW (86 hp) Audi 2.1-litre diesel engine giving a top speed of 70 km/h (45 mph). The Wiesel can ford 0.5 metres (1.6 ft) deep water and cross a 1.2 metres (3.9 ft) wide trench. It was manufactured by Rheinmetall AG.
The chassis is made of steelarmour and can resist common 5.56 mm and 7.62 mmsmall arms ammunition and shell splinters. Air dropping the vehicle from a plane with parachutes was tested, but was not successful; four test-vehicles were destroyed. Nevertheless, the Wiesel can easily be flown in by transport helicopters, a single CH-53 Sea Stallion helicopter can fly in two at once, and common transport planes can carry four or more Wiesel vehicles.
The larger Wiesel 2 has almost twice as much internal volume as its predecessor, and is about 4.78 metres (15.7 ft) long, 2.17 metres (7.1 ft) high (depending on type), and 1.87 metres (6.1 ft) wide.[1] Its weight is approximately 4.78 metric tons (5.27 short tons) in its heaviest configuration.

The Wiesel 2 is a stretched version of the Wiesel 1, with a fifth roadwheel. The engine was changed to a 1.9L Volkswagen in-line four-cylinder turbo diesel with direct injection and intercooler, giving 109 hp (81 kW) coupled to a ZF automatic transmission. The Wiesel 2 is generally bigger, faster and stronger than the Wiesel 1, with advanced features for the protection of the crew such as enhanced armour, an air conditioning system, and NBC protection.
