I don't know to be honest. I don't think so, as there are really not many military pilots compared to commercial? But I'm no expert.
Quickie edit...
Google says the RAF has 1830 pilots and the Navy about 200 more but the UK has over 10,000 commercial pilots. So I guess at least half the commercial pilots trained outside the military. So they're either self funding or getting these employer funded loans?
That hasn’t been the case in decades. When TWA was expanding they had a large pool of WWII pilots. Training for military pilots is very expensive as well. They won’t want to waste it on someone who’s only sticking around 5 years.
