There was a desire to see BeNeLux representation in game and we very much wanted to give it a place too. As has already been explained quite a few times, BeNeLux didn’t have enough practical and viable vehicles to support itself as an independent tree without itself also needing some form of sub tree(s) or something else.
The French tree was the most logical fit and it also helped to satisfy many current and future gaps in the french tree with vehicles France otherwise would not have access too.
I really just wish the Dutch specifically would have been given to Germany. Their ground forces are already integrated into the German army IRL, and it would have been nice to have gotten a F-16AM in the German air tree. I would also argue that France did not need Leopard 2s in their ground tree.
I do wonder though, should we expect more top tier Leopards to be added to France?
Algeria doesn’t use any french vehicle, it’s mostly russian and chinese ones so it wouldn’t make sense. Same for Botswana. The only thing I could find is the Panhard armored car which is probably not even used anymore.
We have a South African Sub tree with multiple unique vehciles and a Rhodesian Hunter. However there is always the possibility of more if a suitable candidate with a purpose arises.
