Currently, military aid to Ukraine comes from 15 countries, Pentagon spokesman John Kirby told reporters.

He confirmed at a briefing that the United States continues to send military supplies to Ukraine, adding that this applies not only to them, but also to 14 other countries. According to him, the United States is confident that these cargoes fall into the hands of the Ukrainian military.

Kirby said U.S. Secretary of Defense Lloyd Austin "ordered the deployment from the United States of an additional approximately 500 U.S. military personnel to locations in Europe to augment U.S. forces that are already in theater."

"These additional personnel are being positioned to respond obviously to the current security environment caused by Russia's unprovoked invasion of Ukraine. And certainly, to help reinforce and bolster deterrence and defense capabilities of the NATO alliance," he said.

"These as all the other ones we've talked about in recent weeks are not permanent moves. They are temporary moves. And we're going to adjust our posture continuously as conditions require. And as President Biden has noted before, we are not and will not send forces into Ukraine," he added.
