The Ottoman army was a powerful fighting force. It fought against European powers. The first time the Ottoman army fought together was in the Battle of Kosovo in 1389. This was against the Serbians.
The Ottoman army was made up of different groups. These groups included the marcher lords, the provincial army, and the Sultan's household troops. They worked together to create a strong battle formation. This formation was used until the end of the 17th century.
The army had different roles. The Azap light infantry were at the front. They were equipped with bows, axes, and polearms. Their job was to slow down the enemy in the middle of the battlefield. The other units of the army would then attack from the sides.
