Model 1981 "Shin'heung" upgradesEarly examples of the Model 1981 "Shin'heung" tank have shown a 9M14 Malyutka (AT-3 "Sagger") anti-tank guided missile installed on top of the turret directly above the main gun, and with two lights on the front of either side of the hull. In recent parades, the Model 1981 "Shin'heung" has been observed with a large IR projector (possibly a reverse engineered copy of a L-2 Luna IR spotlight on the turret, linked to the gun with a brace for elevation, as on the Russian T-55/62 tanks.
The arrangement of the lights on the hull has also changed: there are three lights on the right side of the front glacis (two black ones and one white), plus one on the left side plate; sometimes some of these lights are omitted. The AT-3 "Sagger" missile is also now absent on the PT-85; it's unclear if these new or upgraded variants can be armed with that missile, and if so where the launcher would be installed.
In 2015, Model 1981 "Shin'heung" tanks in parades have also been observed with a Manpad SAM installed on the rear of the turret, as well as three smoke mortars on each side of the turret.
