"Bluestone" used SA army equipment in lieu of British as I recall - small arms & possibly uniforms, can't remember now. A series, knocked on the head with the"new broom" approach of a new broom head of this that or other BBC department (despite Wikipedia's assertions that it's demise was due to other reasons such as the withdrawal of British forces from Afghanistan).
Whatever it's faults I liked it, partly because I recognise all the characters (as with "Auf Wiedersein Pet") from my own army service - I was in the army with all of the characters of both series.
Well, ok, not the female characters, they weren't on issue back then.
