This half-track armoured personel carrier is vehicle, which rests in Czechoslovakia among armoured vehicles the longest time. Nowadays it is sought vehicle by various historical army clubs from Czech and Slovak republic.

In March 1939 Hitler´s Germany occupy Czechoslovak´s Republic and Wehrmacht?s soldiers carried along modern armoured transporters SdKfz.251. This vehicle was developed by company Hanomag as type H kl 6p and this marking resulted in common title ?Hakl? in Czechoslovakia. Our industry capabilities were immediately utilized for army production, so the company Skoda Plzen began producing complete armoured body and company Bohemia in Ceska Lipa began producing chassis. After the end of world war II remained lots of these vehicles and production capabilities for next vehicles. Although after the year 1948 was production of heavy equipment oriented on armament from SSSR, our company could produce own armoured transporter. Because of this decision, BTR-152 were not bought by our army even though these vehicles became a part of equipment of all states from Warsaw Pact.

In 1952-1953 was the company Tatra Koprivnice charged with the change of German engines Maybach by own engines Tatra T-912, that were during that time mounted into new trucks Praga V3S. Two prototypes took part in exams in 1954, but they did not meet the army requirements and therefore the vehicle were reconstructed. New engine Tatra T-928-3 which was used for truck Tatra T-138 was chosen for modernization. Body armour was improved by roof plate. Because of this improvement it was possible to close the vehicle and the interior could be filtrated. A crew did not have to shoot over top, but they used gunports in side armour. The commander had own hatch. Through this cover the man had access to the carriage for universal machine-gun vz.52 with calibre 7,62 mm, later for machine-gun vz.59. New vehicle was developed and from the original german transporter remained only basic construction and outside shapes. Prototype production of 20 pcs run over in Podpolianske strojarne Detva in Slovakia between 1958 and 1959. Since autumn 1959 began serial production of basic armoured transporter version, which was marked as OT-810. Own production run for CSLA (People's Army of Czechoslovakia) needs up to 1962. It was produced about 1500 pcs of different versions. This vehicle was never exported.

Czechoslovak army took up OT-810 especially for transport of mechanized infantry. Crew was created by driver, commander and ten men of infantry. This armoured personel carrier served as transport vehicle for reconnaissance chemical units ahead of OT-65 establishing too. Next extended version were OT-810/R2 and OT-810/R3 that were made in set of 320 pcs. These ones were used as command and signal vehicle, that were determinated for continuous radio contact also during moving for commander, executive officer and tank battalion commander. These vehicles were installed in armament in June 1962. It was also produced about 20 pcs of these vehicles for driver´s training. Some of the vehicles of the basic version OT-810 were modified for vehicles of technical support and for reconnaissance vehicles for artillery during the armoured transporters OT-62 and OT-64 were took up in armament. About 60 pcs of the vehicles were also modified to ambulance version. Carriage was removed and interior was modified for transport of wounded men.

The most interesting modification was version OT-810D, which was light tank destroyer. There were removed a part of roof armour at the back of the vehicle. There were placed 82 mm recoilless rifle vz.59A. The gun protruded above original vehicle ceiling and this space was protected by three folding armoured plates. Back part of the recoilless rifle overreached rear armour, that was straight. OT-810D carried 30 rounds for recoilless rifle. 18 rounds were in supply magazines and 12 were in fighting space. Part of armament were also universal machine-gun vz.59 and personal weapons of the crew. The crew comprised of 4 men. Behind the commander was the place for loader and behind the driver was a place for gunner. The men could place the recoilless rifle on the ground. They also could mount wheels on the gun, which were carried in fighting space. The gun could be used separately if the vehicle was damaged.

The last pieces of armoured transporters OT-810 were eliminated from armament up in 1995. These vehicles did not serve then, but they were stocked in mobilization stores.
