The Object 263 is a Soviet tier 10 tank destroyer.
The development of a heavy tank destroyer on the basis of the IS-7 heavy tank was started in 1950. Three design projects were developed, one of which resulted in a full-size wooden prototype. However, further development was discontinued due to phasing out the IS-7 mass-production.
The Object 263 is a tier X tank destroyer on one of the soviet Tank Destroyer lines. Armed with a rapid fire 130mm cannon, the 263 has the lowest alpha of the tier X tank destroyers but makes up for it with a very high rate of fire and very good accuracy. The front armor on this beast is sloped and very thick, making it very hard to fight from the front. However, enemy tanks will have no problem hitting your sides and rear if you happen to get flanked. Face hugging with other tier 10 tank destroyers is not recommended as your gun mantlet is easily penetrated by very high pen guns, as well as face hugging with tall tanks like the Maus as their guns are mounted high enough to put a shell in your back plate from above. If they load premium rounds, they can mess you up easily. The mobility on the Object 263 is good, with good acceleration and top speed, this allows it to get into position very quickly and support your team. Another very bad weakness to this tank is that it has a large open top, exposing the crew and ammo rack, in return, a direct hit from artillery will really screw up this tank, you will often have to deal with injured crew and damaged ammo racks, and ammo rack detonation.
The Object 263 marks the end of one of the Soviet tank destroyer lines.
