I think it's fantastic that the British/Canadians are training Ukraine soldiers, they are highly regarded and professional forces.
But for the long term... I think the better goal would be to train some Trainer/Presenter/Assessors to make the Ukraine Army more self sufficient, that way they can take on some learned lessons that are more specific to their region, geography and equipment to make them more effective.
It's the longer term stuff that needs to start going into focus.
