The Blockhouse is a military/defensive building in Age of Empires III that is unique to the Russians. It combines the functions of a Barracks and an Outpost by training and upgrading Russian infantry, attacking nearby enemies, and receiving Home City shipments, as well as supporting population.
Blockhouses are resource-friendly, with Russian players only having to pay wood for a fraction of the cost required for a Barracks and Outpost. "TEAM Cheap Barracks" will reduce the cost by 15%, while "TEAM Art of War" reduces it by 10%. If both cards are stacked, Blockhouses only cost 187 wood. However, using this method, Barracks and War Academies will be much cheaper than Blockhouses, at 40 wood and 90 wood respectively, drastically reducing their economic advantage.
Due to Blockhouses' dual-role, losing them will hinder the Russian player's defense and ability to train infantry simultaneously, which can sometimes lead to them being overwhelmed easily during an attack involving siege units.

- In The Asian Dynasties, the Chinese in random map games can build Blockhouses by allying with the Russians at the Consulate, which provides the Blockhouse Wagon shipment that ships a namesake unit capable of building a Blockhouse for free, and allows Villagers to build Blockhouses. Unlike its standard counterpart however, the Chinese Blockhouse train War Academy and Castle banner armies, Flamethrowers, Hand Mortars, and have a build limit of one.
- Revolting to Finland automatically upgrades Blockhouses to Frontier if they are not already for the Russians, and removes their build limit.
- Revolting to Hungary and Romania increases Blockhouses' build limit by one with each Home City shipment.

|“||A blockhouse is a military building that is often fortified for protection. A blockhouse is similar to a fort, but while a fort has multiple buildings, a blockhouse has only one structure. In the New World, blockhouses were used for defense on the frontier. Russian blockhouses built along the west coast were hexagonal in shape and usually had multiple stories.||”|
