Developed in 1945 on the basis of the IS-2 and IS-3 vehicles, under the supervision of Joseph Kotin. One of the distinctive features was the balanced slope angle of armor plates. Passed trials successfully, but never entered service.
The Object 704 has the highest camouflage bonus compared to the other tier 9 tank destroyers, but the weakest armor. It uses the same top gun as the ISU-152, the dreaded 152mm BL-10. With its improved armor, you can engage in close quarter combat with confidence, although this is not advisable due to the long reload time of its gun. Most of the enemy tanks will be able to shoot you twice while you're still reloading. Tactically speaking, being a second line of attack or defense is recommended, as its harder to bring the gun to bear at close ranges (<400m). The Object 704 delivers greater "alpha" strike damage than most tanks, and using this strength can help win the day for your team.
