The Army operates more than 550 Strykers in a variety of configurations. The wheeled and armored Stryker, being supplied to Ukraine for the first time, can be modified to provide medical evacuation or reconnaissance or serve as a nuclear, biological and chemical response vehicle, in addition to speeding infantry squadrons into a battle.
The two armored vehicles serve different purposes. The Bradley brings more firepower, with its cannon and anti-tank missile launchers. The more lightly armored Stryker, because it is wheeled, can move a lot faster on paved roads, meaning it can get infantry squadrons into the fight faster.
The additional air defense systems and ammunition are being sent to help Ukraine defend against the onslaught of Russian missile attacks against its civilian population, the Pentagon said, including a Russian missile strike on an apartment building in Dnipro last weekend that left at least 45 dead, including children.
The $2.5 billion package is one of several recent multibillion-dollar announcements of aid for Ukraine as the U.S. and allies rush heavy weapons to Kyiv in advance of an expected Russian spring offensive. The new aid package brings total U.S. military assistance to Ukraine to $26.7 billion since Russia invaded in February.
Defense Secretary Lloyd Austin is in Germany and will meet Friday with the Ukraine Defense Contact Group, representatives of about 50 countries that coordinate the weapons support.
