I think that one could volunteer for some period and help the MOD pick those ten candidates. But also physical fitness and related criteria. There is also a USMA prep school if you looked through the site. So contacting that school would be worthwhile. Not every military type student might be bright enough to enter West Point.
West Point is now very much a high tech and policy school.
That is it trains engineers on one hand and political leaders on the other. There are some cadets who become tank commanders still. One thing might be informing students of this opportunity if the MOD permitted it. I have the addresses of all these schools. Perhaps it might be possible to help recruit students in regular high schools in Ukraine.
