TEHRAN, Jan. 18 (MNA) – The United States began training Ukrainian forces at Fort Sill military base on the use and maintenance of Patriot missile systems, Pentagon Press Secretary Pat Ryder said on Tuesday.

"Training has begun," Ryder said during a press briefing when asked about the training. "Those troops have arrived at Fort Sill and have begun their training."

The Biden administration is providing one Patriot surface-to-air missile system to Ukraine, to be delivered following the completion of the training. Approximately 90-100 Ukrainian soldiers will be trained over the next several months on how to operate and maintain the missile system, Ryder said, Sputnik reported.

Germany has likewise promised a Patriot missile system to Ukraine, and the Netherlands has expressed its intent to provide one as well.

Western backers of the government in Kyiv have focused their security assistance on air defense in recent months amid Russian missile strikes on key Ukrainian targets.

The Pentagon’s decision to train Ukrainian forces on the missile system at Fort Sill shows the "de facto participation" of the US in the conflict on behalf of Kyiv, Russian Ambassador Anatoly Antonov said earlier this month.

Ryder's remarks come on the heels of reports that American forces have also undertaken military training for Ukrainian soldiers in Germany, which is said to include both field and classroom instruction.
