“This is an opportunity for us to improve our own tactics, techniques, and procedures in cold weather and also an opportunity for us to improve our interoperability with our Ground Self-Defense Force counterparts,” said Col. Jason S. D. Perry, 4th Marine Regiment commanding officer and commander of the Marine Air-Ground Task Force currently participating in Northern Viper.

During this iteration, the combined force will focus on winter combat training, bilateral marksmanship integrated with firepower and maneuver, helicopter diving fire, sniper training, combined arms integration, a Japan and U.S comprehensive bilateral attack, and a Low Altitude Tactics (LAT) insert from MV-22B Osprey.
