The Strv M/21 light tank was a Swedish tank that was designed by Joseph Vollmer, a German engineer who moved to Sweden after World War I.  Vollmer had previously designed the German LK I and LK II tanks, and the Strv M/21 resembled them very closely.

Strv is an abbreviation of the Swedish word Stridsvagn, which means “tank”.

A crew of four manned the Strv M/21. It had a 4-cylinder, 55 horsepower Daimler engine.

The M/21’s only weapon was a 0.256 inch (6.5mm) machine gun.

The command version of the M/21 had a two-way radio, unlike the command versions of the LK I and LK II, which only had radio receivers.

In 1929, the Strv M/29 was built.  It had heavier armor and a more powerful engine – a 6-cylinder, 80 horsepower Scania-Vabis engine – than the M/21. However, the armament was not upgraded.
