Mbh 12.101.2a

"'Bhishma said, "It is proper that those weapons and vehicles should be adopted (by particular bodies of combatants) with which they have become familiar by use. Brave soldiers, adopting those weapons and vehicles, engage in battle. The Gandharas, the Sindhus, and the Sauviras fight best with their nails and lances. They are brave and endued with great strength. Their armies are capable of vanquishing all forces. The Usinaras are possessed of great strength and skilled in all kinds of weapons. The Easterners are skilled in fighting from the backs of elephants and are conversant with all the ways of unfair fight. The Yavanas, the Kamvojas, and those that dwell around Mathura are well skilled in fighting with bare arms. The Southerners are skilled in fighting sword in hand. It is well-known that persons possessed of great strength and great courage are born in almost every country. Listen to me as I describe their indications. They that have voices and eyes like those of the lion or the tiger, they that have a gait like that of the lion and the tiger, and they that have eyes like those of the pigeon or the snake, are all heroes capable of grinding hostile ranks.[303] They that have a voice like deer, and eyes like those of the leopard or the bull, are possessed of great activity. They whose voice resembles that of bulls, are excitable, wicked, and wrathful. They that have a voice deep as that of the clouds, that have wrathful face, or faces like those of camels, they that have hooked noses and tongues, are possessed of great speed and can shoot or hurl their weapons to a great distance. They that have bodies curved like that of the cat, and thin hair and thin skin, become endued with great speed and restlessness and almost invincible in battle. Some that are possessed of eyes closed like those of the iguana, disposition that is mild, and speed and voice like the horses, are competent to fight all foes.
