M-84AS1/2/3
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 tanks into the 2030s and beyond, incorporating domestic innovations alongside some imported components.
