Watchman

Originally, cities and towns were responsible for recruiting and maintaining their own watch organisations. Corruption was so widespread that the Emperor gave the job to the army instead. Now, certain regiments on garrison duty must serve as the town watch. This has cut down dramatically on corruption, though the army itself is not immune. Watchmen are responsible for maintaining law and order and are empowered to make arrests. They also double as fire fighters in smaller towns. For some Soldiers, watch duty is a temporary assignment. For others, it becomes a lifelong career.
