Ukraine now has more tanks on the ground than Russia does, a senior US defense official told The Washington Post.

"Right now, the Ukrainians have more tanks in Ukraine than the Russians do … and they certainly have the purview to use them," the official, who spoke on condition of anonymity, told The Post.

Insider was unable to independently verify this claim, and it is unclear exactly how many tanks both Russia and Ukraine have eight weeks into the war.

But the report comes as Western nations pledged to dispatch more heavy weaponry to Ukraine to help it defend itself against a renewed Russian offensive in the eastern Donbas region.

On Thursday, President Joe Biden announced an additional $800 million military aid package that will equip Ukraine with heavy artillery, howitzers, and tactical drones. The first such package, announced on April 13, included hundreds of armored vehicles and Mi-17 helicopters.

Earlier this month, a Pentagon official told The New York Timesthat the US will help with the transfer of Soviet-made tanks to the Donbas. The official declined to say how many tanks would be sent, or from which countries they would come.
