The U.S. will send Ukraine nearly $3 billion in military aid, in a massive new package that will for the first time include several dozen Bradley fighting vehicles, U.S. officials said Thursday, in the Biden administration’s latest step to send increasingly lethal and powerful weapons to help Ukraine beat back Russian forces, according to AP.

European allies also stepped up their weapons commitments. Germany announced it will provide armored personnel carriers and a Patriot missile battery to Ukraine, and France said it will soon hold talks to arrange for the delivery of armored combat vehicles.

All of the announcements, however, fall short of sending heavier battle tanks, which are more complex to use and have a longer-range gun. The Bradley, an armored carrier used to transport troops to combat, is not a tank but is known as a “tank-killer” because of the anti-tank missile it can fire.

The latest U.S. aid — totaling about $2.85 billion and about 50 Bradleys — is the largest in a series of packages of military equipment that the Pentagon has pulled from its stockpiles to send to Ukraine. It is aimed at getting as much to the Ukrainian forces as possible during the winter months, before spring sets in and an expected increase in fighting begins.
