Romans:
Officer's Quarters
Can only be built in the capital. At level 10, you can upgrade your Praetorians to Centurions. This is a one time upgrade and lasts for the game round.
Centurions gain strength in numbers. For every 100 Centurions trained in a village, their defence is increased by 0.05%. The bonus is maximised at +5% strength if you have 10,000+ Centurions trained in a village.
Additionally, you can use the Officer's Quarters to host Military Parades. These Parades boost morale, and for 24 hours, Centurions move at 9 fields/hour. However, they will become exhausted, and move at only 3 fields/hour for the following 24 hours. You can throw Military Parades in any number of your villages; you use the Officer's Quarters to select which ones.
