US Secretary of Defence Lloyd Austin will convene a meeting of around 50 countries on January 20, 2023 at the US-run Ramstein military base in Germany, including all 30 members of the NATO alliance. The German-made Leopard 2 is seen as one of the best-performing models worldwide and is widely used across Europe, meaning spare parts and ammunition could be easily sourced.
