Cold War: Approximately 1947 (due to U.S. President Harry Truman’s Truman Doctrine) to 1991 (Operation Desert Storm, collapse of Soviet Union).
During the ‘Cold War’, Czech-o-Slovakia was one country created by the victors of World War Two by forcing Slovakia and Czech Republic together (just as they did after World War One). Czech-o-Slovakia became a member of the Warsaw Pact in response to the creation of the North Atlantic Treaty Organization (NATO).
In the Czech-o-Slovak language the BMP became Bojové Vozidlo Pěchoty (BVP), which means basically the same thing as the Russian BMP; Infantry Fighting Vehicle (IFV). Like most users of the BMP/BVP, Czech-o-Slovakia made many different versions, including their unique OT-90.
According to the current Ministry of Defense of Czech Republic (aka Chechia), the OT-90 was developed to carry a squad of infantry equipped with anti-aircraft weapons.
The large turret of the BMP/BVP was replaced with a smaller turret (same used on the Czech-o-Slovak designed OT-64 armored car), to make room for the specialized anti-aircraft weapons.
After the so-called Cold War ended, Czech Republic and Slovakia went their separate ways, and since there was no more Soviet-Warsaw Pact, they both joined NATO (NATO felt it necessary to remain in existence, even though its stated enemy the Soviet Union no longer existed). Today’s NATO-Czechia replaced their OT-90s with NATO-United Kingdom designed Land Rover vehicles. NATO-Slovakia still uses the OT-90.
