From Lexicanum

The Siegfried a light tank used by units of the Imperial Guard.

It is another variant of the famous Land Crawler agricultural vehicle. It is produced in the huge underground factory complexes of Krieg, and was developed during the Krieg Rebellion as a replacement for the Sentinel, whose complex gyro-stabilised locomotive system and light armour were considered unsuitable for the conditions that prevailed at the time. Although no longer used by Death Korps regiments, who prefer to use the more versatile Sentinel, the Siegfried is still utilised in large numbers by siege regiments.

The Siegfried replaces the simple and sturdy catalytic engine of the Land Crawler and Bruennhilde with a considerably more powerful gas turbine engine. The improved power-weight ratio gives the Siegfried almost double the top speed of the Land Crawler, even though it is fitted with considerably more armour. Siegfried tanks are used as a mobile reserve by the Baran Siegemasters, and are also used to exploit breaches in an enemy line.
