Norwegian Armed Forces have released footage from a NATO training exercise called "Cold Response". In the exercise, NATO members train and test personnel how to respond in cold weather conditions. Norway was chosen for the exercise because of its extreme weather conditions which might be unfamiliar and surprising. Around 15,000 miltiary personnel from 14 countries are taking part from February 19 to March 22. The footage released show US tanks sliding around icy corners at speed - training for combat operations in cold weather. An exercise like Cold Response strengthens cooperation between military personnel and participating countries
