We find the following changes in the army at this time :
1. A permanent army was kept by the king or the ruler. This was well organized.
2. Soldiers used different kinds of weapons such as battle-axes, arrows, spikes, spears, barbed dats, swords, iron clubs, javelins, barbed arrows, long arrows, etc.
3. Elephants, Chariots, Cavalry were used along with foot soldiers in the royal ground.
4. Besides, there were military leaders who provided the king with troops whenever he (the king) needed them. They were not paid regular salaries. Instead, some of them received grants of land. They collected revenue from the land and used this to maintain soldiers and horses, and provide equipment for warfare. These men were known as Samanthas. Whenever the ruler was weak Samantas tried to become independent.
