That's being done by making region improvements - structures such as barracks, mines and palaces - exist outside of the city, vulnerable to attack. Generals can no longer afford to hide behind their city walls in the event of an invasion. They must sally forth and chase the aggressor away."
This press release from CA also could allude to it

Empire Images And More Info!

Here's the relevant section

Empire: Total War contains a revolutionised Total War campaign spanning 3 continents and featuring new, enhanced systems for Trade, Diplomacy, Missions and Espionage. There will be an all-new fully animated campaign map with all buildings and upgrades visible. The campaign will also feature a huge cast of historical figures including Peter The Great, Malborough and Charles XII of Sweden. The game will include 10 playable factions including Britain, Prussia, France, Spain, America and the massive Ottoman Empire.
Of course that could just be referring to the UI and not a barracks somewhere in a province.
