'infantry cannon wagon 91', was a high mobility assault gun that was developed to meet the operational requirements of the Swedish Army.

Additional armament of the ikv 91 included two 7.62 mm Browning machine guns; one in a coaxial mounting, and the second on a pintle attached to the commander's cupola.

The vehicle was equipped with a laser rangefinder, night vision (goggles) and a computerised fire-control system for increased first-round hit probability.

Screens would be erected to stop water from entering the engine and the cabin compartment with a vane to protect from oncoming waves.

The ikv 91 was retired from the Swedish army in the late 1990s – early 2000s due to budget cuts among others and was partly replaced by the strf 90 combat vehicles and Leopard 2 tanks.

During the 1980s it became clear that the low velocity HEATFS-firing gun of the ikv 91 was not up to the task of fighting the new generations of Soviet made tanks.

The idea was put on hold until the 1990s when it became obsolete as the role of the ikv 91 could be filled by new strv 122 main battle tanks and strf 90 infantry fighting vehicles.
