With some 50,000 troops and tens of thousands of vehicles, ships, and aircraft, exercise Trident Juncture 2018 was NATO's largest exercise since the end of the Cold War.
"NATO does a major exercise like this each year," Ben Hodges, who commanded the US Army in Europe before retiring in 2017, told Business Insider earlier this year. "The scale of this one obviously is bigger than some of the past, but nonetheless, the fact that this exercise is happening is a normal part of NATO's battle rhythm."
In 2017, NATO conducted 108 exercises, and its members held 162 national and multinational exercises. This year, the alliance had 106 NATO exercises planned, and its members were expected to lead about 180 national and multinational exercises.
Those exercises vary in scope, duration, and form, ranging from live exercises involving thousands of troops to computer-assisted exercises in a classroom.
Below you can see just a few of the exercises NATO conducted this year with its members and partners.
