I won't go through the whole of my father's service record, what info I do give, you may find interesting.
1. Enlisted in 1940 as an aircraftsman/general duties.
2. December 1940 reports to Padgate, Warrington for medical examination.
3. January 1941 reports to Blackpool recruits centre for basic training in the use of rifle and gas mask. he then went to Morecombe recruit centre for further training.
4. March 1941 stationed at RAF West Kirby. At the same time he is attending Police HQ Uxbridge for training. he was then posted to N048 unit Hawarden, Flintshire. Here he undertook duties of airfield and camp security and liaised with local Police.
5. December 1944 posted to Mediterranean Allied Air Forces at Portici, Italy. Sometime later he was posted to Malta.
6. March 1946 discharged at Hednesford/Cannock camp.
Whilst stationed in the U.K the 'Military Police' would have been protecting the camps, bases, airfields and any other installation from untoward activity such as drunkenness/theft etc. They would also have to go to the local towns and round-up the late returners to camp. A few examples of what my father did but I am sure there were many more duties he had to carry out.
