Research improved steel grades for cuirasses

Research improved steel grades for cuirasses is an upgrade in Cossacks 3, available at the Academy.

Background
At the close of the 17th century, cavalry armour was fundamentally changed. It became smaller, had no bracers or leg-guards and sometimes did not even cover the back. Owing to its smaller size, the armour's thickness was increased. This fact, along with the use of more durable steel grades, allowed bullets and cold steel to be repelled with greater efficiency.
