just make sure when fighting someone 1 on 1 if you're gonna brawl (not what the is-3 is for tho) you are straight on against them, it's like the is-7 with the angled front armor. never angle in the is-3/is-7
If not brawling, what is it for? That's 90% of what I do w/the thing so far.
The IS-3 is an enjoyable tank. It's a fun brawler and the BL-9 makes it deadly and dangerous. It's in every way shape and form better than the IS, which was fun by itself as well.
The 2nd turret makes side shots at your turret hurt less at the cost of some frontal turret armor.
Does the 2nd turret have some glaring weaknesses on the front? B/c on paper it has 220mm armor vs 150mm of the first turret...
