After winning the main game, the British leave (except for Templar forts) and US soldiers replace them. However, if you haven't completed the "Liberation Missions", playing them after this will have the US soldiers in place of the British. NPCs will refer to them as "redcoats". See more

The enemy advances and you tremble. They've better numbers, you say. Better weapons. Better training. But I do not fear, and neither should you. For what they have in material, they lack in conviction and care. But not us. We have discipline. We have order. And most importantly, we have passion. We believe! So maintain vigilance. Conserve your ammo. Ensure a proper line of sight. And above all else, men, do not fire until you see the whites of their eyes.
