What is an army and what functions does it perform?

The army is the armed forces aimed at protecting the state. There is an army in every country. The armed forces are divided into separate troops, each performing a specific task, but there are functions common to all. In peacetime, soldiers ensure the security of the country’s borders, identify threats in a timely manner, and engage in military training. In the event of hostilities, the army repels attacks from external and internal sides, protects the citizens of the country, and holds the occupied territory.
