In this video, you can see a life demonstration of the recent technology used by the NATO army.
NATO has twenty-eight members, mainly in Europe and North America. Some of these countries also have territory on multiple continents, which can be covered only as far south as the Tropic of Cancer in the Atlantic Ocean, which defines NATO’s “area of responsibility” under Article 6 of the North Atlantic Treaty. During the original treaty negotiations, the United States insisted that colonies like the Belgian Congo be excluded from the treaty. French Algeria was however covered until 3 July 1962. Twelve of these twenty-eight are original members who joined in 1949, while the other sixteen joined in one of seven enlargement rounds. Few members spend more than two percent of their gross domestic product on defense, with the United States accounting for three fourths of NATO defense spending.
