http://royalpioneercorps.co.uk/rpc/ As he was a Sergeant in the AMPC in 1940 I would say he may have been a Reservist called back up, the Pioneers Corps was the Cinderella of the Army, composed of reservists from a mixture of Infantry & Cavalry Regiments, elderly volunteers of First World War vintage & who in some minor degree fell short of the physical standard demanded of first line troops, there was 20,000 Pioneers in France in December 1939 alone. Indifferently administered and with little or no military training, its influx of recruits was pitchforked into France to join the B.E.F. and meet the full impact of the German attack of May 1940.
In Nov 1940 the Auxiliary Military Pioneer Corps was renameded the Pioneer Corps, in Nov 1946 it then become the Royal Pioneer Corps, a fact that in the long and glorious history of the British Army on other Corps or Regiment has earned this signal honour in so short a period of time.
Hope this helps you, I was a Pioneer for 22years in the British Army and very proud of the fact that Men like your G/F defended this Country. in its hour of need.
Pioneer 1985-2006
