- Strong frontal hull armor and turret armor
- Great gun handling and DPM
- 3rd highest standard penetration of all heavy tanks (default ammunition is APCR!)
- Superior top speed and less weight than IS-7, giving it excellent mobility similar to mediums
- High speed and good armor make it good for ramming
- Turret has a cupola weakspot unlike the IS-7's turret (it is small, though).
- Lower plate is easily penned like the IS-7's, but the thick beak from IS-7 is absent.
- Armor is preangled, like on IS-7, so angling makes UFP much weaker.
- Extremely low HP pool for a heavy tank, tied for 2nd worst HP pool out of all tier X heavies.
- Requires completion of all four sets of Personal Missions to earn.
