M-84AS1

The M-84AS1, M-84AS2, and M-84AS3 are modernization programs for Serbia's fleet of M-84 main battle tanks, which are Yugoslav-era variants of the Soviet T-72. Developed by Serbia's Military Technical Institute and produced by the Technical Overhaul Institute "Čačak", these are primarily upgrade packages rather than new-build tanks which aim to extend the service life of the Serbian Army's aging M-84 fleet into the 2030s and beyond, incorporating domestic innovations alongside some imported components. Unveiled in 2017, the programs focus on enhancing firepower, protection, mobility, and situational awareness to counter modern threats like tandem-warhead anti-tank missiles and drones.
