Bhagavad Gitā, XVIII.43
Kshatriy-s were physically strong, well-trained in the art of warfare, and use of weapons. One of them would become the king. In the days of king Bharat, the ruler was selected on the basis of his knowledge and capabilities. The king’s primary responsibility was to protect the population, provide for necessities of life like food, water, schools, roads, etc. Other Kshatriy-s would be in the army.
