Basic Armor is a technology that can be researched at the War Center in Tech Level 2. It costs 100 Food, and gives Troop Center units +1 armor and +1 pierce armor. It must be researched before Light Armor becomes available.

It is useful for players and civilizations that rely on Troopers, and its cost is low.

"This Tech Level 2 upgrade gives all Troop Centre units a bonus to their armor, which helps defend them against both ranged and close-quarters attacks."
