Need help with names of important RAF individuals

[Greyman]

Specifically what their initials stood for. Thanks for any help.

- Group Captain R.M. Field

- Wing Commander C.P. Brown (Air Ministry Department of Operational Analysis)

- Wing Commander C. Walter (67 Wing AASF)

Sorry for the thread necromancy. I had discovered information on Wing Commander Brown (Colin Peter) and figured I'd bump the thread and ask again for help on the two remaining.

All I see is "R. M. Field" with various ranks. There was one Roswell Martin Field, but he served in the US Armed Services in the 1800's, not in the RAF in WWII.

 

[N4521U]

Could be Roger Martin Field. A page I found.
