I won't be discussing Premium tanks, this is for the regular tree only and I won't be discussing SPAAGs either. Which needs to consider a few things such as which kind of opposition the US tanks face, the efficacy of armor, ammo, guns, mobility and etc. The main point here is to evaluate the BR gaps, which line ups are the most effective and which ones are actually fun to play at. The 1.71 updade made some major changes that mostly impacted the US high tiers. So after spending some time on both low and high tiers after this update I think any US main players or anyone planning to grind the US tank tree should be aware of how each line up from rank II onward behaves.
