World of Tanks Supertest: IS-M Details

2 min read

The first vehicle of the new Soviet mini branch will be the IS-M, also know as IS-2SH. The design is a modernization variant of the IS-2 proposed by N. Shashmurin in early 1944. The project didn’t receive any development as the IS-6 (Object 252) project began.

Players will be able to research this vehicle on the tech-tree, no details from what tank the new branch will start but I strongly believe it will be from the Tier VII IS tank.

  1. wow…. much novelty, even more content in the soviet tech tree. Just what we needed. looks like wg cant find the balance between new content, and maintaining the previous.

  2. Looks like WoTB is now an unofficial huge supertest server for everyone because we had the IS-2 Sh, they also balanced gold rounds, added twin-barreled tanks (i.e. Helsing HO), ATGMs, brand new premium tanks (not fantasy tanks but tanks like Kpz 70, Blaze WZ {AKA WZ 135G FT} and Churchill VI) and premium tank balances… So go on to Blitz go get quick leaks and balance?

  3. Also, as I forgot to mention, we got a new equipment system and a new currency called spare parts, new camo, an additional equipment slot called provisions where you could put food and other stuff, and I’ve also heard they are adding the Chieftain. In addition to that, we have some of the best seal clubbing tanks still in the game (although not to their actual potential like in PC) i.e. T18 and T82, we kept the FV4202 and it’s ammo load out of APCR, HEAT, HESH… Feels like they are managed by different companies… Which platform do you think is better, Blitz or PC?

  4. I personally welcome any new non-premium tanks , especially ones which are actually novel. We currently don’t have a T8-10 rear mounted turret line so this could actually be really interesting.
    The IS-M is going to be the absolute king of side scraping with 120mm of angled side armour although the low pen and low accuracy will be a little tricky.
    Colour me interested in this and the rest of the line.

  5. We kind of do have a rear mounted turret line in the German tech tree with the VK45.02b the Pz.Kpfw VII. The IS-M can also draw comparison to the Chrysler K (although premium, not a tech tree tank)

  6. Is the IS-M worth grinding and playing thru because otherwise i will just gold my way to the obj 705 tier 9
