Service with RASC in India

[Milmed]

Hi,
I am helping out a neighbor to piece together her fathers service during WWII.

He had shared very little information with the family except that he had served in India and finished up as a Major. She did mange to find in his things, Officers Record of Service, Army Book 439.

I have managed to extract the following out of it and hope someone could expand on the information or add to it.
