WORLD CIVILIZATION

Detailed explanation-1: -The Indus people certainly did have serviceable weapons of copper-alloy materials including knives, spears, and arrow heads (many have been found) and there are depictions, for example, of a man spearing a water buffalo so the concept of attacking with a spear is certainly present.

Detailed explanation-2: -Copper and bronze were the principal metals used for making tools and implements.

Detailed explanation-3: -Note: Indus Valley artisans and blacksmiths produced a wide variety of utilitarian and decorative objects using specialised techniques of stone working and metallurgy. Materials like Ceramic, bronze and stones were used to make tools, mirrors, pots and pans.

Detailed explanation-4: -In addition to the bow and arrow–the chief weapon–they used javelin, axe, and sword. Horses were common but were probably used to pull the chariots rather than for riding.
