Hi Tod
The badge with Lightning flashes suggests Radio ?Operator, the epaulette bars suggest an Officer. Is it possibly a Civilian Airline Uniform? A lot of military tunics have patch pockets but often with brass buttons, although Navies do often have the slit pocket even where there is a breast pocket as shown on your picture, . Your experience is greater than mine but my impression of military uniforms is that cap and other badges(such as the ?wings in your photo)would have a clearer indication of Nationality such as a Crown, eagle or the like or RAF,USAF etc. My experience was RAF and contact with USAF and Commonwealth Air Forces post WW2.
