Portugal ordered 50 E.B.R.s and 28 ETTs in 1956. After the outbreak of the Portuguese Colonial War, most of these vehicles were sent to Portuguese oversea territories for counter-insurgency operations, especially Portuguese Mozambique. During the Carnation Revolution, an E.B.R. 75 FL10 of the Armed Forces Movement confronted an M47 Patton crewed by loyalist troops in the Praça do Comércio. The crews of both vehicles eventually stood down without incident.
