On December 2, the United States announced a new $725 million military aid package to Ukraine, which includes a shipment of anti-personnel mines, munitions for high-mobility missile systems (HIMARS) and other artillery systems, Stinger missiles and drones.
Washington announced the first shipment of anti-personnel mines last month, which US Defense Secretary Lloyd Austin said was necessary as Russian forces began using infantry units instead of advance vehicles.
Ukrainian defenders "have a need for things that can slow down that progress," Austin said.
The administration of US President Joe Biden is working to provide additional aid to Kiev before President-elect Donald Trump takes office.
Trump has repeatedly criticized American aid to Kiev.
US Secretary of State Anthony Blinken called the new aid package "a significant package of urgently needed weapons and equipment" in a statement.
