T49
At Tier 9 it can be a bit sketchy as to whether or not you’re going to be bottom tier, despite this, the T49 is a beast of a Light tank that performs like no other when facing against Tier 10 opponents. This little USA LT is one of the highest alpha damage Light tanks in World of Tanks, boasting a huge 700 alpha damage (or 910, depending on the shell type) with 152 mm of penetration. So long as you aim for those weak points and hit a tank flat-on, you'll have no problem performing when at bottom tier.
