Members of the British armed forces from the Royal Navy, Royal Air Force and Royal Marines

Military forces (often called the military when specific to a certain group) are a group or groups of people that are given power to defend a country or territory with weapons. They are armed, so they are called the armed forces. The military protects its country by defending it from the armed forces of enemies, if there is a war. The military can also be ordered by the government of the country to attack another country. The word "military" comes from Latin miles, warrior.
