I calculated the total RP and SL required to unlock every vehicle in each nation’s ground tree, including foldered vehicles and squadron vehicles. These graphs show the full cost of completing an entire tree from start to finish.
I also included a minimum grind path version that only counts the required vehicles you need to reach top tier. Once you remove the foldered and optional vehicles, the rankings shift a lot and some nations become far faster or slower than they appear in the full-tree totals.
