In March 1939 there was only one TNH P-S that was completed, with eight others in production when Germany took over Czechoslovakia.4 In May 1939 the German Army extensively tested the TNH P-S.4 It was found that it was basically equivalent to the PzKpfw III.4 By then nine were completed and were designated the PzKpfw 38(t).4
Originally the PzKpfw 38(t) had the Czechoslovakian 3.7 cm gun, but this was replaced by the German 3.7 cm KwK L/45.8
The Germans ordered that the armor be increased to 50 mm in front, the sides to 30 mm, and the turret had a total of 50 mm.9
In late May 1939 contracts were issued to CKD of Prague (renamed Böhmisch Mährische Maschinenfabrik AG9 or BMM) for 150 tanks.4 These would be the Ausf A.4
The Germans wanted production to be at 40 per month.9

Waffenträger: Weapons carrier. It was to carry and then dismount various types of guns. Two prototypes were completed and production was to start in mid-1945. The engine was moved to the front near the driver. This made room in the rear for the carrying of additional ammunition. Two models were to be produced, one to carry the 88 mm PaK L/71 or the 105 mm light field howitzer. The other model was lengthened and was to cary the 128 mm K 81 gun or a heavy field howitzer. Also used as reconnaissance vehicle, ammunition carrier, and artillery prime mover.
