4. Chemical / Biological warfare

The hindu gods had these various "astra"s ..
like parjanyastra - which creates horrendous rains in the enemy terretory,
agniastra - created fire in enemy terretory,
sarpa/naag-astra - the arrows supposedly had their mouths like serpents and vomit forth fire all around.

To tackle these astras the counter astras where something like..
pavan/vaayu-astra - which blew away all the clouds created by parjanyastra or diminished the fire created by agni-astra.
Garudastra - was to tackle the naag-astra where the arrows The arrows becomes Garudas and cut off the serpent arrows on all sides. Garudas are the enemies of serpents.
