Progetto M35 mod. 46, as of May 2020
The Prog46 is an interesting tank for a potato. While it's a rather difficult tank to really master, due to the auto-reloader mechanism, it's a pretty easy tank to at least do "something" with.
If all you do in a game is empty a clip into someone, hide to reload, and empty another clip before dying, you've likely contributed a lot more damage than you would have in most other tier 8 medium tank as a potato.
The Prog46 has no armor, so in order to do really well it requires map awareness, knowledge of camouflage and bushes, and knowledge of the maps, but if you just follow another medium to support him, get in a few shots, and then empty your clip before dying you've done something at least.
It also happens to be THE meta-medium for Frontlines (currently), and if you're in a potato clan doing Stronghold it's also the meta-medium there.
The really great thing about it is, that you can do "something" in it every game while learning, and the better you get the more you can use the full potential of the tank.
Potato score: 6.5 / 10 potato (for the potato that wants to improve).
