Ukrainian Defense Minister Reznikov said on social media on the 13th local time that Ukraine received a batch of US-made "Stinger" air defense missiles from Lithuania.

However, the date on the box label of this batch of "Stinger" missiles is "December 31, 2010", which has caused media speculation about whether the missiles are nearing the end of their use or have expired.

  In addition, Reznikov also confirmed that earlier on the 13th, Ukraine received another 180 tons of ammunition from the United States for use by the Ukrainian armed forces.

It is said that so far Ukraine has received 17 batches of nearly 1,500 tons of ammunition.

  On February 2, the United States ordered the deployment of nearly 3,000 additional troops to Poland and Romania, of which about 1,700 American troops were sent to Poland.

On the 11th, a senior U.S. defense official confirmed that the U.S. Department of Defense had decided to send an additional 3,000 troops to Poland.

  On the 13th, another group of U.S. soldiers and equipment arrived at the Rzeszow military base in southeastern Poland near the Ukrainian border. In addition to military transport aircraft, the U.S. military also used a civil airliner.

In addition, a U.S. V-22 "Osprey" tilt-rotor aircraft also landed at the Rzeszow military base.
