When it comes to tanks, for example, the International Institute for Strategic Studies (IISS) recently approximated that Russia had lost slightly over 2,000 tanks. The losses have been particularly concentrated among Russia’s more modern tank models—its inventory of T-72B3 and T-72B3M have been halved since the war began. For the T-80BV/U, the losses are closer to two-thirds of the pre-war total. Currently, the IISS estimates that Russia has about 1,800 operational tanks at its disposal, although another 5,000 older and lower quality tanks are likely in storage and might be deployed if necessary. Oryx, a different outfit composed of independent analysts that has been attempting to track losses in the Ukraine war using open-source intelligence, claims that Russian tank losses are just over 1,700.

The data released by the Ukrainian Ministry of Defense goes on to claim that Russia has also lost 2,086 UAVs, 2,433 artillery systems, 250 anti-aircraft systems, 873 cruise missiles, and almost 500 multiple launch rocket systems.

But it’s not just Russia losing military equipment to Ukraine. The spigot of Ukrainian aid is a serious drain on the United States’ military stockpiles.
