I had just reported aboard B-1/10 at GTMO in December 1973, newly graduated from the Basic Field Artillery Officer Course at Fort Sill. We were a composite battery down there, 105mm and 155mm howitzers. I was the billet of105mm howitzer platoon commander. We had just completed my first FIREX when I gave the command “MARCH ORDER” No one moved. I was stunned, and thinking what now lieutenant! Then my platoon sergeant gave me a nod and yelled out “CSMO”, and as any Marine 08 knows, the platoon was a blur of movement. Lesson learned.
