The IT-1 was a Soviet anti-tank missile carrier designed with the intent of being fielded as a mobile and effective anti-tank weapon system. It was developed in the 1960s and was based on the chassis of the T-62. It was equipped with a 3M7 'Drakon' ATGM specifically designed for the vehicle. The missile had a range of up to 3 kilometers and could penetrate armor up to 500mm thick. The radio-based SACLOS guidance system used by the IT-1 allowed the operator to guide the missile using any one of the seven given frequencies and two codes. While the idea sounded promising, the IT-1 was criticized for a number of reasons, including the weight of the guidance equipment, the complexity of the guidance system, and the significant deadzone around the tank caused by the missiles' minimum range. Unfortunately, these flaws contributed to its widespread unpopularity, which ultimately caused the IT-1 to be phased out after only five years.

The IT-1 was introduced in Update 1.59 "Flaming Arrows" and was one of the first ATGM-equipped vehicles to be in the game. The IT-1 is a niche modification of the T-62 chassis with a new, low profile turret designed to carry a 3M7 Drakon ATGM launcher, which is the vehicle's only weapon system and mounted above its turret. The IT-1 isn't very survivable, so it's best used at long ranges and ideally behind cover to lessen its vulnerability. However, keep in mind that the ATGMs take some time to reach their target, and people who are aware of your presence can easily shoot them down.
