18MAY2021, Slovenian M84 fires a shot during NATO wargame Adriatic Strike-21.

The M84 was a Cold War Yugoslav upgrade of the Soviet T-72 using ‘western’ tech (Yugoslavia was not part of the Warsaw Pact).  The visual give-away is the wind sensor on the center-front of the top of the turret, just above and behind the main gun.

These photos show Slovenian M84A4s during the U.S. Army’s (USA) Combined Resolve XV wargame, in Hohenfels, Germany, which took place from February through March 2021.

The A4 ‘Sniper’ upgrade improved the day/night gun sight and the fire control (ballistics) computer.  There are unconfirmed reports that the ‘Sniper’ is powered by a German made motor.

USA happy-happy-joy-joy ‘interoperability’ video report, by Sergeant Joseph McDonald, about building a turret down defensive position for M84 on Hohenfels, Germany, February 2021:

In the early 2000s, former Yugoslav member Slovenia upgraded their M84s to M84A4s and called them Sniper.  The ‘A4 Sniper’ upgrade was created by former Yugoslav member Croatia, which operates a factory that has built M84s since the days of Yugoslavia (former Yugoslav member Serbia also builds upgraded versions of the M84).

The Republic of Slovenia became a member of NATO in March 2004.
