The VII ISU-122S is the combination of an IS hull with a powerful 122 mm cannon. The result is a powerful tank destroyer with solid alpha damage, fast reload time, and one of the highest DPMs of its tier. Paired with a nice top speed and a low profile, you can either go on the offensive and seek out weaker opponents, or support the advance of your team as part of a wolf pack.
Be careful not to get caught off-guard as you are not the nimblest. Your frontal armor consists mostly of the gun mantlet, which fortunately has a reasonable size. Don’t miss your chance to add this gem with serious damage potential and a zero perk “Brothers in Arms” crew to your Garage.
