I do recall contemporary newsreel of the street fighting in Athens, when the tiny British force was surrounded and fought desperately. I am sure the narrator commented fighting Germans in Italy and flown to Athens to liberate an Allied city to find themselves fighting for their lives. Less certainly I think the initial troops were paratroopers.

There ia short succint chapter on the Greek Civil War in 'Intervention and Revolution by Richard J. Barnet (pub. 1972), which mentions 75,000 British troops being deployed. The footnotes refer to Edgar O'Ballance's 'The Greek Civil War' (pub. NY 1966), who was an ex-British Army officer.

Oddly Field Marshal Michael Carver's book 'Britains Army in the 20th Century' does not mention this! Scanned a few books here, nothing.
