Serbia Sharpens Armored Edge as Modernized M-84 AS1/2 Tanks Train for Breakthrough Operations.

Serbia is strengthening the combat readiness of its armored forces as crews from the 15th Tank Battalion trained with modernized M-84 AS1/2 main battle tanks during tactical and live-fire exercises designed to rehearse breakthrough operations against enemy positions. The drills, announced by the Serbian Armed Forces on June 23, 2026, demonstrate Belgrade’s effort to translate its tank modernization program into battlefield capability by improving offensive maneuver, fire accuracy, and crew survivability.

The exercise showcased the upgraded M-84 AS1/2’s enhanced sensors, fire-control systems, protection suite, and mobility, enabling crews to engage targets while moving and from short halts under combat-like conditions. By pairing modernized tanks with realistic training, Serbia is reinforcing heavy armor as a key element of its land forces while adapting legacy platforms to meet the demands of modern, high-intensity warfare.

On June 23, 2026, the Serbian Armed Forces announced that members of the 15th Tank Battalion of the First Army Brigade had conducted tactical training and live-fire exercises with modernized M-84 AS1/2 tanks at the Pasuljanske Livade Training Ground. The activity marks another step in Serbia’s effort to convert tank modernization into practical combat readiness. More than a routine firing event, the exercise highlighted how Belgrade is preparing its upgraded armored units for faster maneuver, more accurate fire, and higher survivability in a changing regional security environment.

During the multi-day training, Serbian tank crews performed tactical and fire missions in conditions close to real combat situations. According to the Serbian Armed Forces, the main focus was on sudden and forceful breakthroughs through enemy dispositions, combined with the engagement of different targets while moving and from short halts. This emphasis is significant because it reflects the core battlefield role of main battle tanks: delivering shock action, maintaining momentum under contact, and exploiting firepower during offensive armored maneuver.

The use of the modernized M-84 AS1/2 gives this training a broader operational meaning. The platform retains the 125 mm main gun of the M-84 family, but its modernization package is intended to strengthen the three pillars of armored combat power: firepower, protection, and mobility. Army Recognition reported that the upgraded tank integrates improved sighting and observation systems, a remotely operated 12.7 mm weapon station, additional armor, active optoelectronic protection linked to laser and radar warning sensors, smoke grenade launchers, second-generation explosive reactive armor, day-and-night driver vision, GPS navigation, and a day-night DNNS 2ATK sight with thermal imaging or a digital fire-control system.

These upgrades are especially relevant to the way the Serbian crews trained at Pasuljanske Livade. Firing on the move and from short halts depends not only on gun power, but also on target acquisition, stabilization, fire-control quality, and crew coordination. Army Recognition’s previous analysis underlined that Serbia’s current training cycle is aimed at turning sensors, protection, and mobility improvements into faster engagement cycles at unit level. In practical terms, the M-84 AS1/2 is not simply an older Yugoslav-era tank with new equipment; it is being shaped into a platform better suited for night combat, reduced exposure time, improved situational awareness, and more resilient direct-fire maneuver.

At the regional level, the strategic implication is clear: Serbia is seeking to preserve a credible heavy armored capability without waiting for a full fleet replacement. By modernizing the M-84 through domestic industrial and technical capacity, Belgrade strengthens both its armored formations and its national sustainment base. In the Western Balkans, where geography favors rapid ground maneuver across relatively short distances, the ability to field trained crews on upgraded tanks can reinforce deterrence, increase operational confidence, and signal that Serbia intends to keep heavy armor as a central component of its land forces.

However, the modernization should be viewed with balance. The M-84 AS1/2 improves the combat relevance of Serbia’s existing tank fleet, but it does not erase all limitations of an older design lineage in an era of drones, loitering munitions, precision artillery, and top-attack anti-armor weapons. Its real value will depend on how many vehicles are upgraded, how consistently crews are trained, how well the tanks are integrated with reconnaissance, engineers, artillery, air defense, and command-and-control systems, and whether sustainment and ammunition stocks can support prolonged operations.

The live-fire training at Pasuljanske Livade shows that Serbia’s M-84 AS1/2 program is moving beyond modernization on paper toward operational use in the field. By training crews to break through enemy positions, engage targets under movement, and operate under combat-like pressure, the Serbian Armed Forces are demonstrating that armored readiness remains a strategic priority. For the region, the message is unmistakable: Serbia is investing not only in upgraded tanks, but in the trained crews and tactical doctrine needed to make them matter on a modern battlefield.
