context_page_description: The OT-64 SKOT is an amphibious, armored personnel carrier, developed jointly by Poland and Czechoslovakia well into the 1960s.
  Until the early 1970s Czechoslovakia produced around 4,500 OT-64 SKOTs of all variants, just under a third of which were exported.
context_section_description: The OT-64's engine, transmission, suspension and axles were produced in Czechoslovakia. The engine was produced by Tatra. The gearbox was manufactured by Praga Hostivař. It has a pre-select Praga-Wilson gearbox, (5 forward +1 reverse gears.) A gear is selected using the gear stick then when the gear is required the left pedal (gear change action/clutch combined) is pressed to the floor, giving a hiss of air sound, on release of the pedal the dry plate clutch engages after about half the return spring controlled movement. The drive then passes to an auxiliary gearbox with low, neutral and high ratios which needs to be selected before moving off, for road/neutral/off-road use, this gives option to the driver of 10 forward and 2 reverse ratios. The gear change pedal is hydraulic and on action opens an air valve which causes the selected gear to engage. The armored hull and weapons were produced in Poland.
  The OT-64 was the answer to the Soviet BTR-60. Contrary to this, the OT-64 used a diesel set in place of a petrol engine. That diminished the danger of fire and at the same time increased the range. The main advantage in relation to the Russian counterpart was the full-armored interior. The entrance is at the rear of the vehicle via twin doors. The OT-64 had an NBC protection facility and night-vision equipment. It also has central inflation for all wheels which can be controlled by driver during a drive. The OT-64 was air-transportable and amphibious, for the transport on water used two propellers installed at the back.
  Several variants were built. Some OT-64 were re-equipped for air defense or built as tank hunters. The latter used the AT-3 Sagger missile as a weapon.
