How was armour during Mahabharata?

Most references appear to point to what would be called Mail.

Coats are “weaved”, they “dangle” and “tear” during battle, they're fairly good but can be “broken” and “repaired”, warriors use arrows and armour-piercing weaponry like maces but swords are also common. And of course, they literally call their Armour so.

Eminent Historians whine that this is a sign of the Mahabharata actually being have been written in the Classical Age, probably under the Guptas- even though the Guptas clearly would've been as likely to use Scale and, again according to the same Eminent Historians, were supposed to be hidebound superstitious Hindu Nazis who had a moratorium on any form of Scientific and Cultural change. Lel.

As far as I know, the oldest historical findings of Mail date back to the 4th Century BC- roughly 1600 years after the most recent dates for the Mahabharata, so possibly the intellectuals might've had a viable and internally logical argument - if they weren't so quick to describe references to Mail in the Rig Veda as spurious while blindly accepting the ones in the Avesta as legitimate.

As for Archaelogical evidence - Rolfmao. I'm not aware of anyone finding any coats of Mail in Orissa either, even though Oriya armies fielded troops with thousands of armoured soldiers as late as the 1700s.
