Mahabharata Virat Parva Chapter 31:2

Mahabharata Virat Parva Chapter 31:2 Give thou unto them cars furnished with banners and let them case their persons in beautiful coats of mail that should be both invulnerable and easy to wear. And let them also have weapons. Bearing such martial forms and possessed of arms resembling the trunk of mighty elephants, I can never persuade myself that they cannot fight.' Hearing these words of the king, Satanika, O monarch, immediately ordered cars for those sons of Pritha, viz., the royal Yudhishthira, and Bhima, and Nakula, and Sahadeva, and commanded by the king, the charioteers, with cheerful hearts and keeping loyalty in view, very soon got cars ready (for the Pandavas). And those repressers of foes then donned those beautiful coats of mail, invulnerable and easy to wear, that Virata had ordered for those heroes of spotless fame. And mounted on cars yoked with good steeds, those smiters of hostile ranks, those foremost of men, the sons of Pritha, set out with cheerful hearts. Indeed, those mighty warriors skilled in fight, those bulls of the Kuru race and sons of Pandu, those four heroic brothers possessed of prowess incapable of being baffled, mounting on cars decked with gold, together set out, following Virata's wake. And infuriate elephants of terrible mien, full sixty years of age, with shapely tusks and rent temples and juice trickling down and looking (on that account) like cloud pouring rain and mounted by trained warriors skilled in fight, followed the king like unto moving hills. And the principal warriors of Matsya who cheerfully followed the king had eight thousand cars, a thousand elephants and sixty thousand horses. And, O bull among the Bharatas, that force of Virata, O king, as it marched forth marking the footprints of the cattle looked exceedingly beautiful. And on its march that foremost of armies owned by Virata, crowded with soldiers armed with strong weapons, and abounding in elephants, horses and cars, looked really splendid."
