The U.S.-Dutch-Czech consortium announced the $90-million deal on Friday “in response to Russia’s continued aggression against Ukraine, and in support of the valiant efforts of the Ukrainian armed forces to defend their sovereign territory.”The 1980s-vintage tanks will come from the inventory of the Czech defense industry, according to the three governments.The 90 T-72Bs the Americans, Dutch and Czechs are providing should raise the overall quality of the armor the Ukrainians are acquiring from foreign sources.The ex-Czech T-72Bs could replace the T-72Bs that existing Ukrainian brigades have written off since the war widened back in February.Alternatively, the Ukrainian army could form three new 30-tank battalions and assign them to some of Ukraine’s current light or medium brigades, adding protection and firepower to those units.The third option is for the Ukrainian army to stand up a new tank brigade—something the service so far has declined to do despite the central role its five or six tank brigades have played in Kyiv’s war plans."
