I am a F2P player and on occasion will buy a Christmas lootbox or the like. I have a number of premium tanks from events etc…but have only spent actual $ on the Scorpion way back when. I have tanks including Tier X. But I don’t shoot gold ammo at all, and try to excel at the game from that perspective. I have 2 marks on a few tanks, close on a couple of others, and am an average player.

Is it possible (realistically) to 3 mark a tank without using gold rounds?

Thanks! Keep on tanking.
