The U.S. will send a Patriot surface-to-air missile system to Ukraine to bolster its air defense capabilities, a move that represents one of the most advanced defense systems that the Americans have so far provided to support Ukraine since Russia invaded last winter.
The transfer is part of a $1.85 billion package of new military assistance to Ukraine announced amid a months-long Russian assault on the country's critical infrastructure as the long, cold winter season sets in.
