Chart with max upgrade levels for all tanks, and all tank unlock requirements. I have updated an earlier one that someone else built, and added missing info, added Tier 8 tanks, and corrected errors from similar chart a couple years old. Currently still need screenshots of higher levels of upgrades for 2 tanks, and screenshots to verify max levels for 2 more tanks.

I've shared this on the "Official " Facebook page, hundreds of players have thanked me for compiling this info into 1 chart. Many players have told me this is their "Go - To source" when making decisions on a new tank purchase. All I ask for is help in completing this chart. I would like to have accurate data proven by screenshots on all tanks maximums, in 1 place - to help others when making those tank purchase decisions.
