Chieftain tank
In 1965, Israel's military establishment began research and development on a domestically produced tank, the "Sabra" (not to be confused with the later model of the same name which is now in service, see: Sabra tank). Initially, Britain and Israel collaborated to adapt the United Kingdom's Chieftain tank that had entered British Army service in 1966. However, in 1969, Britain decided not to sell the tank to Israel for political reasons.
