Developed by ČKD for the needs of the Czechoslovak Army in 1938. During the German occupation was in service with the Wehrmacht. As part of German tank units, it was used in the Polish and French campaigns, as well as on the Soviet-German front. In the combat units of the first line was used until mid-1942. Around 1,400 tanks were produced in eight versions (Ausf A / B / C / D / E / F / S / G).
History ordered that the production of LT vz.38 began when the army of Czechoslovakia ceased to exist. After the German occupation in March 1939, the tank was adopted by the army of invaders. In the Wehrmacht, the car received the designation Pz.Kpfw.38 (t) Ausf.A (simplified names are also widely used – Pz.38 (t) or 38 (t)). It is interesting to note that the Germans did not have any information about TNHPS before the occupation of the Czech Republic and Moravia.
But German experts were able to appreciate the fighting qualities of the new tanks. In the period from May 2 to 6, 1939, the Arms Management Commission worked at the ČKD plant under the leadership of Lt. Col. Olbrich, who was responsible for the development of promising models of armored vehicles. The commission quickly decided to purchase for the Wehrmacht all 150 units previously ordered by the Czechoslovak army. Ten days later, the German military reception began working at ČKD, which was soon renamed by the Germans as BMM (Böhmisch Mährische Maschinenfabrik AG). The last tank from the first series was adopted by the Germans on November 23, 1939.

The legendary tank during operation had several modifications:
- The first tanks were called PzKpfw 38 (t) Ausf.A
The German army received 150 Pz.38 (t) Ausf.A tanks of this series. These machines were almost completely identical to those intended for the Czechoslovak army. With a mass of 9.7 tons, they were armed with a 37 mm A7 gun (the German designation is KwK A7) with a barrel length of 42 calibers and two 7.92 mm machine guns vz.37 (in the Wehrmacht – MG 37 (t)). Ammunition consisted of 72 rounds and 2700 rounds.
6-cylinder in-line engine of liquid cooling Praga EPA with a capacity of 125 liters. from. allowed the tank to reach a maximum speed of up to 48 kilometers per hour. Cruising range – 230 km. The tank was equipped with a Praga Wilson six-speed planetary gearbox and a multi-disc main dry friction clutch.

The chassis included four rubberized road wheels of large diameter on board, suspended in pairs on semi-elliptic leaf springs, two support rollers, a front-wheel drive wheel, a steering wheel and a steel track. The thickness of the frontal armor of the hull reached 25 millimeters, onboard – 15, aft – 12, roof – 10, bottoms – 8 mm. The armor protection of the tower ranged from 15-25 millimeters.
After receiving the German army of tanks PzKpfw 38 (t) Ausf.A. Tanks almost immediately upgraded and converted to their own standards. In the German version, the crew of the tank was 4 people. Armor performance was also improved. They reinforced the ballistic installation of the ballistic machine gun and installed their own radio equipment. In the original Czechoslovak version, the tank was equipped with a vz. 37 radio station with two antennas – a pin. Having saved the latter, the Germans installed their Fu 5 radio station. In addition, German-style ammunition boxes were used.

- Modification of the tank PzKpfw 38 (t) Ausf.В
Tanks modifications Ausf.V were produced from January to May 1940. During this time, 110 cars were produced. They eliminated the handrail antenna, mounted the German headlight Notek, slightly changed the embrasure of the gun sight. On some tanks already in the troops, for example, in the 19th Panzer Division, smoke exhaust devices were installed.
- Modification of the tank PzKpfw 38 (t) Ausf.C
This series also consisted of 110 units and was produced from May to August 1940. Combat vehicles of modification C were distinguished by the presence of a German-style radio antenna, a modified location of the muffler and ring armor of the tower epaulet.
- Modification of the tank PzKpfw 38 (t) Ausf.D
In the design of 105 tanks of modification D, released in September – November 1940, taking into account the experience of military operations in Poland and France, the frontal plate of the hull was changed. Now it has become direct, and on the part of the vehicles its thickness has been increased to 50 mm, reinforcing the standard 25 mm armor with an overlay of the same thickness.
