This Info Flash outlines the challenge that Russian main battle tank (MBT) developments, the T-14 Armata now challenges all of NATO’s platforms. With the war in Ukraine signalling that conventional warfare is far from over, NATO must re-evaluate its armoured capabilities. The capabilities of the Russian T-14, the American M1 Abrams, the German Leopard 2, the British Challenger 2, the French Leclerc, the Italian C1 Ariete, the Polish PT-91 Twardy, and the upcoming Turkish Altay are investigated in order to understand why the United States must choose between what it is accustomed to in the Abrams or move on to something entirely new. Simultaneously, the bilateral relationship between France and Germany is taken into consideration for understanding the need for inviting other European states into its Main Ground Combat System project.
