President Joe Biden is sending Ukraine $800 million in new firepower -- including artillery, helicopters, ammunition and other military hardware that will test the limits of how far aid can go without drawing the U.S. directly into the war.
Biden announced the new package on Wednesday after an hourlong phone call with Volodymyr Zelenskiy. It includes heavy artillery systems and armored personnel carriers, signaling a more intense military commitment from what began as shipments of more defensive materiel.
