Ships 15 Old Guard Grenadiers. Any remaining Middle Guard are upgraded to Old Guard.
—In-game description

Imperial Old Guard is a technology in Age of Empires III that is unique to the French and can be researched at the Church once the Industrial Age is reached, the Edict of Nantes Home City Card has been sent, and Imperial Middle Guard is researched. Once researched, 15 Royal Guard Grenadiers named Old Guard will appear in the Home City shipment point and the previous twelve Middle Guards (if they still remain) will be upgraded to Old Guards.

Imperial Old Guard, along with the previous Imperial Young Guard and Imperial Middle Guard, is the only way for the French to acquire Grenadiers. In the Definitive Edition, however, the French can train Grenadiers once the "Grenade Launchers" Home City Card is sent. Researching Imperial Guard technologies will effectively upgrade the Grenadiers to Veteran and Guard levels automatically along with automatically adding the Incendiary Grenades technology.
