Hmm, USMC has ~195,000 serving personnel + 40,000 reserves, with land sea and air forces.
We have, what, 185,000 serving personnel + 36,000 reserves across all three services?
I have no idea how many orifices there are of star rank in the USMC, but I can't imagine it's anywhere near the combined total of our three services.
I'm sure a major platform is going to be cut, very probably from the raf - along with associated redundancies.
