According to my logbook, signatures in 1969 show that Derek Bryant was OC 1 Sqn and Ken Hayr was OC 2 Sqn (both Sqn Ldrs at the time). So in those days 1 Sqn did the conversion, air defence and combat training and 2 Sqn did the ground attack and recce training. I think that ground school and sim was 3 Sqn. Engineering was centralised and came under Wingco Eng (and that, another story!!)
