-The '''ISU-122S''' was an improved design of the [[ISU-122]] (rather than a separate variant) assault gun used by the Soviets during World War II, mostly in the anti-tank role. A semiautomatic breech block has been fitted to the original 122 mm A-19S tank gun. The tank gun with this new design was designated as the 122 mm D-25S. The modification resulted in an increase in the fire rate to 3 rounds per minute from 1.5 rounds per minute. The ball-shaped gun mantlet and double-baffle muzzle brake of the ISU-122S are distinguishing features. The Germans coded the ISU-122S as Type 249 in their official reports.

-Introduced in the Closed Beta Test for Ground Forces before Update 1.41, the ISU-122 is a long-range sniper that performs well in combat due to its high penetration, accuracy, and good reverse speed. Locate a good spot to snipe from and engage the enemy from a distance to keep them from approaching the objectives. Due to the high profile and inadequate frontal armour, one should always stay away from the frontline to avoid being flanked or swarmed. Although there is a significant reduction in reload time, players should still make their shots count since most enemies reload much more quickly, making it impossible to take a follow-up shot if the initial shot misses.

 The ISU-122 were organized in units in a similar fashion as the [[ISU-152]]. The focus was made to not mix the two vehicles in the same regiments or brigades due to logistical reasons with ammunition and ballistic differences in indirect fire, but some units were equipped with both vehicles anyways. Like the ISU-152, the ISU-122 proved to be a very powerful multi-purpose vehicle as an assault gun, self-propelled artillery, and tank destroyer. The 122 mm gun on the ISU-122 allowed it to engage armour and fortifications with heavy armour-piercing round and a large high-explosive round. The primary role of the ISU-122 was as a tank destroyer due to the gun's superior ballistics compared to the ISU-152's, which large calibre size more suited its role as an assault gun. The ISU-122 did participate as an assault gun role in urban combat to support the infantry, but the lack of rotating turret and long barrel length restricted its manoeuvring and ability to engage all enemies in a large angle. Nevertheless, commanders found the ISU-122 as a very good assault gun. Usage of the ISU-122 in an indirect firing role as a howitzer is rare, but when used could fire up to 14 kilometres away. Usage as an artillery piece is more likely during a rapid offensive where towed artillery behind the lines is unable to keep up with the advancing infantry lines.
-=== In-game description ===
+{{break}}
 The ISU-122S self-propelled gun was created in April 1944 as a modernised variation of the ISU-122 SPG. It differed from the latter in that it was equipped with a 122 mm D-25S Mod. 1944 cannon with a wedge-type semi-automatic breech block and a muzzle brake. The barrel's length came to 48 calibres. The height of its firing line came to 1,795 mm. The vehicle had a five-man crew and its crew housing was the same as in the ISU-122. The use of this cannon increased its rate of fire in combat from 2.2 to 3 shots per minute. The cannon's new compact recoil mechanisms and breech housing provided better working conditions for the combat crew. Artillery superiority over the enemy had been absent for some time, but the use of the D-25S cannon brought it back. It had higher combat characteristics than the German 75 mm and 88 mm weapons, and penetrated enemy tank armour at a range of up to 2,500 m. In urban battles however, the 122 mm cannon's barrel length often prevented the vehicle from manoeuvring in tight spots.

 In the middle of the 1960s, the SPGs were removed from service in the Soviet Army.

+Based on the IS-2, the {{PAGENAME}} has its robust chassis, wide tracks and powerful engine. It benefits thus from the same good mobility despite being a relatively heavy vehicle. The acceleration is good and it will reach its maximum speed without any problem.
 The very high reverse speed allows it to back off from an engagement quickly, once shot at or spotted. The wide tracks give it good handling and performance on soft terrain. The {{PAGENAME}} is quite sluggish in stock condition, especially when turning on the spot. And because of its weight, it is slow when going uphill. If you have to turn quickly on the spot, privilege using your reverse gear because it has more torque.
@@ Line 181: / Line 181: @@
 ;Offensive role
 The {{PAGENAME}} performs well as a long range sniper, taking advantage of the APHEBC shell's high penetration values, high gun accuracy and good reverse speed. Find a shooting spot and engage targets from at least 1,000 m away to prevent enemy progress towards the objectives. Because of its high profile (casemate), long reload, and weak frontal armour, always stay away from the frontline to avoid being flanked or swarmed. While your gun is very powerful, your in-game performance will highly be dependent on the map you are playing on. Open maps like Fire Arc, Kursk, or Maginot Line will allow you to make the best use of its sniping capabilities, whereas urban environments like Advance to the Rhine are generally poor maps for the {{PAGENAME}}. In case you are playing on a mixed terrain map, prefer open spaces.
 ;Defensive role
 In case of an enemy breakthrough, your role is to contain the enemy advance by pinning them down. The enemy will be moving the front line, so engagements will take place at a closer range than you're comfortable with. You should identify and target priority choke points, narrow passages, and corridors of the map that the enemy will be forced to take. Your limited gun traverse only allows you to monitor an area spanning about 175 m at 1,000 m distance without having to reposition your hull. Position the left side of your casemate behind an obstacle to leave only your gun mantlet exposed, the thickest part of the frontal armour.
 ;Other roles
 If you try to use the {{PAGENAME}} in a different role on the battlefield, you will be confronted with the following:
 * If you try to play as a front-line tank, you will be quickly disabled by any type of fire coming from enemy tanks. Your frontal armour is pretty thin for a tank to play at close range, and a successful penetrating shot from the front will usually disable your crew sitting in a line. Your gun traverse is very limited and your turning speed is also too poor to manoeuvre quickly enough in close combat.
 * If you attempt to play support tank, your high profile will make it difficult to stay hidden behind obstacles without taking fire. Your good reverse speed can be an advantage but the enemy will flush you out with an artillery strike (which can be accurate enough at medium range to disable you). Even with an escape route planned and cover to hide behind, your chances of survival are meagre. You will also be at risk of being flanked by light tanks or armoured cars, especially if they swarm you. Anyone who manages to get behind you has a very high chance of destroying you. In that role, an undetected flanking enemy, artillery strikes or CAS will be great threats to the {{PAGENAME}}.
