The Indian Army and Indian Air Force are the AT4's fresh clients from Sweden's SAAB. SAAB's Carl-Gustaf system has been in use by the Indian military. TheIndian Armed Forces chose the single-shot gun in a fair market.

SAAB, a Swedish manufacturer, is supplying the Indian Armed Forces with the AT4CS AST. This may be shot from tight locations such as bunkers, within buildings, as well as in other urban settings. This Swedish corporation is involved in the design, manufacture, and maintenance of sophisticated aeronautics technologies, sensors, undersea systems, weapons, command structure, and so on. The AT4CS AST tandem warhead has a breach or explosion mode. According to the company's public announcement, this mode is geared to demolish constructions that can establish a type of entry inside them and eliminate adversaries within buildings.

On January 20, 2022, the Swedish corporation inked a deal of the agreement on its webpage. The deal was signed by FFV Ordnance AB, the branch in charge of the industry's Ground Combat offering in India.
