This lines up with the information in the Vigano essay:

In March 2015, Ukrainian Interior Minister Arsen Avakov announced that the Azov Battalion would be one of the first units to be trained by US Army troops, as part of their Operation Fearless Guard training mission. US training was discontinued on June 12, 2015, when the US House of Representatives passed an amendment banning all aid (including weapons and training) to the battalion because of its neo-Nazi past. The amendment was then revoked under pressure from the CIA (here and here) and the soldiers of the Azov Battalion were trained in the United States (here and here): “We have been training these guys for eight years now. They are really good fighters. That’s where the Agency’s program could have a serious impact.”
