Specifically, the mismatch in crew values caused by commander's 10% crew skill bonus. Outside of a crew of 1 commander only, 100% crew is a fiction. The client values, given for 100% crew, will normally be taken into battle with 110% crew skill members aside from specific functions, causing their actual performance to deviate from the expected client value. These differences are taken into account in tooltip boxes.

The Strv fm/21 is a Swedish tier 1 light tank.

The LK II tank was developed in Germany in 1918. The vehicle underwent trials, and the German army placed an order for 1,000 tanks. However, the order was not completed before the end of World War I. In 1920, Germany sold 10 LK II vehicles to Sweden, which entered service under the designation Stridsvagn fm/21. In 1929-1932, the vehicles underwent modernization and received more powerful engines and improved frontal armor. All modernized vehicles were designated Stridsvagn m/21-29 and were used for training purposes until 1940.

The Strv fm/21 leads to the Strv m/38.

Historical Info

Following the war, the Swedish government purchased parts for 10 examples in secrecy for the sum of 200,000 Swedish kronor. The parts were shipped as boiler plates and agricultural equipment and then assembled in Sweden as the Stridsvagn m/21 (Strv m/21 for short), which was essentially an improved version of the LK II prototype. The Strv m/21 was powered by a sleeve valve type engine located in the front, the driver and crew being in the rear. The suspension and running gear was protected by armored skirts. Ten of these tanks were built and were armed with a single 6.5 mm machine gun.

In 1929, five were rebuilt to create the Strv m/21-29 variant which was armed with a 37mm gun or two machine guns and was powered by a Scania-Vabis engine. The Strv m/21-29 was an upgraded version of the fm/21. The modifications included a more powerful engine, a new alternator, and external lighting. One of these improved vehicles was driven by Heinz Guderian during a visit to Sweden in 1929. The Germans later bought a main share of the Landsverk Company and made Otto Merker the main designer and in 1931, it produced the Strv m/31 (L-10), which was the first tank produced in Sweden.
The Strv m/21-29 remained in service until 1938. A surviving example can be seen at the Deutsches Panzermuseum at Munster, Germany, and both strv m/21 and strv m/21-29 was displayed at the Axvall Tank Museum in Sweden.
One Strv m/21-29 is in the early stages of being restored to full working order in Sweden.

Historical Accuracy Errata

The following are consensus errors or inconsistencies which have been identified with the configuration of the vehicle in question and conflict with information available on the public record. The causes for these divergences in the game are normally not disclosed and may be rooted in game balance.

Its maximum speed of real life vehicle is only 16 KM/H. But for making this vehicle not underpowered from its very low speed in same tier, Wargaming decided to increased this vehicle speed to 25 KM/H which it's most of tier 1 max speed.
