In the above photo, the KF-51 "Black Panther" main battle tank from Rheinmetall in Germany is performing the "traditional show" of German main battle tanks - the gun barrel glass. In another video, accompanied by the figure of the KF-51 "Black Panther" main battle tank speeding through the forest, the wine glass placed at the top of the barrel remained steady on the muzzle without spilling a drop of wine. The "gameplay" of the gun barrel wine glass originated in Germany, and the earliest related video that appeared online was the scene of the Leopard 2 main battle tank gun barrel wine glass. The reason why the Germans came up with this special way to dazzle their skills is to visually show the mobility and stability of the main battle tank of Panther 2. The Leopard 2 main battle tank is a main battle tank developed by Germany in the 1970s, known for its maneuverability and firepower. The Leopard 2 main battle tank has developed multiple models, including A1 to A7, and is equipped in multiple European countries. In recent years, although the Panther 2A4 main battle tank equipped by Türkiye's army was destroyed in the conflict, this type of tank has a good reputation in Europe on the whole. When NATO held tank shooting competitions, more than half of the countries used Leopard 2 series main battle tanks to participate, and their results did not fall below the top three. The KF-51 "Black Panther" main battle tank is a new type of main battle tank launched by Rheinmetall in recent years, planned to replace the Leopard 2 series main battle tanks equipped by the German army. Although the KF-51 "Black Panther" main battle tank and the Leopard 2 main battle tank are produced by different companies and have no "blood relationship", in terms of performance, the KF-51 "Black Panther" main battle tank "inherits and carries forward" many advantages of German main battle tanks. Firstly, both use the same power system, and the KF-51 "Black Panther" main battle tank has a smaller body weight and stronger maneuverability. Secondly, the KF-51 Black Panther main battle tank has stronger firepower. The 130mm smoothbore gun equipped on it surpasses the 120mm gun of the Leopard 2 series main battle tank in terms of firing rate, range, and armor piercing capability. Thirdly, based on recent regional conflict combat experience, Rheinmetall has also equipped the KF-51 "Black Panther" main battle tank with unmanned aerial vehicles, installed active and passive defense systems, and armored perspective systems to help it seize the initiative in future battlefields. From this perspective, although the KF-51 "Black Panther" main battle tank is very different in appearance from the Leopard 2 series main battle tank, it has a clear German main battle tank imprint on its body, showing the continuous relationship between "Black Panther" and "Leopard". Looking at the photo above again, you can glimpse the "leopard" in the picture. (New Society)
