Prototype Tanks*
*
The LT vz.38 unit, also known at the time as the CKD TNH Prototype, was designed by CKD (Ceskomoravska Kolben Danek) for export. When the Czech army called for companies to submit designs and models to replace the trouble plagued LT vz.35, the TNH was chosen. Later this tank would be known the the LT vz.38. This design was rigorously and extensively tested, and it was known for it's reliability. It had no serious defects. Modifications were made by the Czech Army and the tank was renamed to the LT vz 38. After German occupation, CKD's name was changed to BMM (Bohmisch Mahrische Maschinenfabrik). One prototype was built, plus 50 more for export to Iran.*

Two original prototypes of the ST vz.39 unit were produced for trials and ready in 1938. It was also known as the CKD V-8-H. The Czech army had approved this model for production but the breakup of the nation prevented it. One production prototype of the accepted design was ready for the Czechs in 1938 and another in 1939 for the Germans. The Germans tested the prototype but did not produce the model.*

This formation is included for hypothetical scenarios involving a Czech-German War, and also for use in hypothetical Iranian scenarios. The Czechs produced several other prototype tanks during the period between 1935-1939, and these two can be used to simulate them as well. Some of these prototypes were: CKD P-II-a, CKD P-II-b, Skoda S-II-b, Skoda CKD SP-II-b, Skoda S-II-c, Skoda SP-III, and the Tatra T-III.*
