The 38(t), originally known as the ČKD LT vz. 38, was a tank designed during the 1930s, which saw extensive service during World War II. Developed in Czechoslovakia by ČKD, the type was adopted by Nazi Germany following the annexation of Czechoslovakia. With the German Army and other Axis forces, the type saw service in the invasions of Poland, France and the USSR. Production ended in 1942, when its main armament was deemed inadequate. In all, over 1,400 Pz. 38(t)s were manufactured. The chassis of the Pz. 38(t) continued to be produced for the Marder III (1942–1944) with some of its components used in the later Jagdpanzer 38 (1944–1945) tank destroyer and its derivative vehicles. The (t) stands for , the German word for Czech; the Czechoslovak military designation was LT vz. 38 (, Light Tank model 38). Manufacturer's designations included TNH series, TNHPS, LTP and LTH. The special vehicle () designation for the tank in Germany was Sd. Kfz. 140. Description The Panzer 38(t) was a conventional inter-war tank design, with riveted armour. The armour varied in thickness from 10 mm to 25 mm in most versions. Later models (Ausf. E on) increased this to 50 mm by bolting on an additional 25 mm armour plate to the front portion of the hull. The sides received an additional 15 mm increase of armour from Ausf. E production runs onward. The two-man turret was centrally located, and housed the tank's main armament, a 37 mm Skoda A7 gun with 90 rounds of ammunition. In addition, a 7.92 mm machine gun was in a ball mount to the right of the main gun. This machine gun could be trained on targets independently of the main gun, or coupled to the main gun for use as a conventional coaxial machine gun. The driver was in the front right of the hull, with the radio operator seated to the driver's left. The radio operator manned the hull-mounted 7.92 mm machine gun in front in addition to operating the radio on his left. Minor adjustments, such as adjustable seats for the driver and firmer footing for the commander/gunner and loader, were provided in German service. A total of 2,550 rounds were carried for the bow and turret machine guns. The driver could also fire the hull machine gun with a trigger fitted on the left tiller bar. In German service, a loader position was
