The Pantsir-S1 is a Russian SPAA designed with the intent of complementing and enhancing the existing air defence capabilities for military, industrial, and administrative installations. The development of the Pantsir-S1 can be traced back to the early 1990s, when the Russian military realised it needed an adaptable short-to-medium-range air defence system. The Instrument Design Bureau (KPB Tula) and the Ulyanovsk Mechanical Plant worked together to develop the Pantsir-S1. The main objective was to develop a highly adaptable and powerful anti-aircraft system that could take on a variety of aerial threats, such as helicopters, fighter jets, and drones. It features advanced radar systems and a combination of missiles and guns for effective air defence. Additionally, the system is equipped with a high degree of automation, allowing for quick reaction times and efficient target engagement.

The Pantsir-S1 was introduced in Update "Sky Guardians" as a top-tier SPAA vehicle. In terms of gameplay, the Pantsir-S1 excels at engaging aircraft and helicopters at medium to close range. Its combination of missiles and autocannons allows it to deal with various aerial threats effectively. However, its armour is relatively thin, so players need to be cautious about enemy ground units. Nonetheless, the Pantsir-S1's mobility and versatility ensure that it can provide effective air defence support to friendly forces.
