Weapons with edges like plough-share were known as halamukhani. These were of wood, bamboo, horn or metal and varied in length from two to eight feet. A bow was the main offensive weapon of a soldier. In the early times it was made of Palmyra - tola, bamboo - chapa, wood and bone or horn - singa.

Different weapons were used in different wars. For example, swords were meant for close-quarter battles and were of many varieties. The handles assumed ornamental shapes and were made of horns of rhinoceros, buffalo, and tusk of elephant, wood or root of bamboo.

Tavernier has observed that in ancient times gunpowder was first discovered in Assam from where the knowledge was passed on to Burma and other countries. A long cylindrical pipe - nalika was used and fired like a gun. There was a hole in the rear to ignite the gun-powder. This machine was employed for throwing stones. A sharp point at the front tip of the barrel was used for aiming purposes. Besides these there was a bigger machine which was carried on a carriage. This gun piece fired a ball. All this indicated the active use of gun-powder at the time. Armour or kavach for the protection of the body was made of steel plates, steel-wire nets, skin or cloth. Senior commanders had their armour studded with precious stones. It could cover the whole body including the hands - hastaghana and head - sipra.

All the weapons used in ancient Indian Army were kept in safe places and cleaned at regular intervals. The Superintendent of Armoury also known as Ayudha-garadhyaksa was made responsible for ascertaining the demands of the various weapons, their utility in battle and wear and tear with a view to consequent improvement and manufacture. After a campaign the weapons and other allied stores were returned to the armoury. The Superintendent of Armoury was also responsible for the building and defence of forts and making plans for the devastation of the cities or strongholds of the enemy.
