Just find it curious that the French, West Germans, and Americans get IFVs while the Brits don't.
Two possible answers:
1/ we are devious anti-British activists, and have been retaining the Warrior
just to annoy our dear neighbours, even more than defeating them at the incoming Six Nations game next week.
2/ we kept to the game's timeframe (1975-1985).
--> introduction of the AMX-10P
in French service: 1973
--> introduction of the Marder
in German service: ~1971
--> introduction of the Bradley
in US service: 1981-1982
--> introduction of the FV103 Spartan
in British service: 1978
--> for the record, introduction of the FV510 Warrior
in British service: starting 1985.
Besides, there was still the FV432
that we didn't retain either and which was much more widespread in the British Army than the Warrior
