Every country has armed forces which help to defend the country against external threats that arises now and then in the form of war or trying to get into an area of the country forbidden to external people or foreigners. The armed forces are trained extensively to defend the nation and to keep the people in the country safe and secure.
The armed forces are mainly of three types, namely the army, navy and air force. Each operates on separate topographies and is trained to defend from different angles. For example, if there is a threat to the country, the army is not the only force which would come to defeat it. There would be defenders from the air force and the navy.
The army consists of the group of people who defend the country from land. These people are trained vigorously to defend the country from external aggressors. They have skills in the artilleries like the AK47, etc and other guns which can be quite powerful and rare. They are the most well known and popular people among the three defenses of the armed forces.
The air force is other armed forces which defends the country from the air. These are the people who risk their lives in the air to defend their country from any threat that arises. The objective of the air force, from a defensive point of view is to conduct aerial warfare when the need arises. It is a form of advanced way to defending the country.
The navy is a force which defends the country through the water bodies. These people are also involved in trade and foreign relations. They are extensively trained to be skilled and efficient when the need arises. The navy is usually forgotten by people as a part of the armed forces but the fact is they are quite important.
