Hi g2shoes,
I agree with bleckie to apply for your fathers service records. If he was in the RAF would he be commanded by Colonel Slim, who was in the army? Unless Slim commanded all the forces, both army and airforce.
If you obtain the Squadrons your dad was attached to you could have a look at the site rafb24.com which has details of most of the squadrons that served in India and Burma (including some photos of personnel).
good luck - let us know how you get on
regards
Brian
