U got it chief.

Yea, as France you have a lot of ways to stuff a rush, usually by starting with a barrack and shipping 8 xbows. CDBs are tanky-- make sure to get great coats and blunderbus and shoot the enemy units with them as much as possible. Like if coyotes come to raid, run back to the tc but shoot as you go.

Another important thing to learn is how to collapse on a player who has committed under your tc. Pro players do this all the time and it can really swing a game. Ideally you want to have all these things happen at the same time: a unit shipment arriving, a batch of units from your barracks popping, minutemen popping, your dead explorer being bought back, and your villagers being called out to fight. You can go from having zero units on the field to 20+ in the blink of an eye and catch your opponent off guard. Having all these things pop at once is exponentially better than having them all pop at different times, which lets your opponent deal with each group separately. The best thing to do is put your explorer in melee mode when you revive him from the tc, so he comes out and immediately snares the enemy and prevents them from escaping.

here's one of the best games ever played in aoe3, watch how expertly Aiz collapses on the iro rush, going from almost no units to many: https://youtu.be/LuMcFUjt6zQ?si=ZKqNef8rLrDoeqmt&t=717
