LCpl as the pongos couldn't understand SAC - with no aircraft.
Flt Lts used to run sqns with only one wg cdr and one sqn ldr. In the RAF the concept of the overborne sqn ldr led to rapid rank inflation and job creation.
In 1968 one sqn ldr might be 1st RO for 50 JO. The following year with sqn ldr leaders as 1st RO for 10-12 each.
When I meant rank pruning I meant across NATO but accept that some micky mouse countries might need air commodore sqn cdrs.
One cruise ship I was on the captain wore the rank of a vice-admiral. The following year I saw he was a rear-admiral! British shipping companied tend to have just one commodore for the whole fleet.
