A U.S. Air Force C-130 air drops a pallet of supplies to Ukrainian army soldiers taking part in Exercise Rapid Trident 2017 at the Yavoriv Combat Training Center on the International Peacekeeping and Security Center in Western Ukraine. After the supplies landed, soldiers from the 1st Battalion, 95th Separate Airmobile Brigade closed in on the drop zone to secure the supplies. Rapid Trident is an annual, multinational exercise involving approximately two thousand personnel from 14 nations. The exercise is composed of a multinational, brigade-level, computer-assisted command post exercise integrated with a battalion-level field training exercise and platoon-level situational training exercises. The exercise will also include integrated, aeromedical evacuation and tactical airlift and airdrop training. Rapid Trident 2017 supports joint combined interoperability among Ukraine, the U.S., and allied and partner nations. (Photo by Spc. Samuel Mason, 45th Infantry Brigade Combat Team)
