Newport, RI 2017
This armory is the home of the Artillery Company of Newport whose members have served in wars from the French and Indian Wars right up to the war in Iraq. The company was chartered in 1741 by King George II and is the oldest military organization in the United States still operating under it's original charter. Today the company serves primarily as the ceremonial unit of the Rhode Island Militia, Council of Historic Military Commands and provides canon salutes, color guards, and honor guards for state events. I've read that anyone can join, and that no prior military experience is necessary.
