Raises all your troops to Guards if they are not already.
—In-game description

Petrine Reforms is a technology in Age of Empires III that is unique to the Russians and can be researched at the Church once the Industrial Age is reached, the Reformist Tsar Home City Card has been sent, and Westernization is researched. Once researched, Strelets, Musketeers, Halberdiers, Cossacks, Cavalry Archers, Oprichniks, and Grenadiers are upgraded to the Guard/Royal Guard level (if they otherwise are not yet).


Petrine Reforms allows the Russian player to save 5,000 wood and 2,500 coin. It is recommended to research this technology as soon as possible to get the most from Russian units.
