“More than 170 Ukrainian military soldiers have been trained at more than one location on the M777, and there’s another 50 plus that is scheduled to graduate today, so when they do graduate today — in fact, they may have already graduated today — that puts us up over 200 Ukrainian artillerymen trained on the M777.”
“Another 50 plus” Ukrainians will be arriving at one of the training sites outside of Ukraine later this week to begin training on the M777 Howitzers. In addition, a group of 20 Ukrainian soldiers began a week-long training course on the Phoenix Ghost UAV systems on May 1,” the official added.
Over the last 24 hours, 13 flights of US security assistance to Ukraine have arrived in the European region, and an additional 11 flights from the US will arrive in the region over the next 24 hours.
