By the end of 2023, Kyivs forces had retaken only a fraction of Russian-occupied ground.
The Leopard 2 has proven to be an extremely potent MBT, easily among the finest of its generation.
It has been noted for offering a unique blend of firepower, protection and mobility.

However, the partnership ended shortly after as the three nations sought different needs.
The Leopard 1 proved to be rather more substantial than the original concept had envisaged.
The Leopard 1 went through a series of evolutions, with some 4,200 MBTs produced in all models.

In addition, its chassis was employed in ARVs (armored reconnaissance vehicles) and the Gepard anti-aircraft tank.
As had occurred with the Leopard 1, West Germany went on to independently develop its successor.
At around 55 tonnes, the Leopard 2 was considerably heavier but not that much bigger.

The engine and transmission were located at the rear of the hull.
The rest of the running gear was nearly identical to that of the Leopard 1.
In addition, another MG3 was installed on the loader hatch for use in an anti-aircraft role.

According to German military sources, nearly all of the previous models were upgraded to the 2A4 standard.
Development has continued enough that the newest variants are essentially a generational leap forward in capabilities.
Denmarks tank unit also earned high praise from other NATO partners.

Despite the losses, the Leopard 2 has proven to be a capable MBT in the ongoing fighting.
