This was reported by RIA Novosti with reference to a senior representative of the US Department of Defense.

He said the US and its allies have developed a "sophisticated and efficient" supply mechanism that has been used for "many weeks".

“We are talking about eight to ten flights to the region per day and almost constant ground convoys that move into the country.

We would like to keep it,” the Pentagon said.

At the same time, the ministry did not disclose the details of the logistics mechanisms.

Earlier, the Pentagon said that a group of Ukrainian military personnel had received training in the United States on the use of the Switchblade loitering kamikaze drones, which Washington supplies to Kiev.
