JAS
My understanding from talking to a friend with RE, who I trained with is:
The yr 1 FO starts on 28K and remains on 28K for the rest of his or her career as an FO. No payscale. No increments.
If he/she becomes a Capt, starts on 50k, and remains on 50k till retirement. No payscales. No increments. No pension. I think L2A's Command figures were slightly excessive.
