In May 1939 the Navy Department donated a 4.7 field piece to the Post. This gun was transported to the Post Lot on Colonial Avenue across opposite the Dance Pavilion in June. In October 1939 the field piece was moved the triangle of property across from the Catholic Church, said property being owned by the Town. The Post also placed blocks under the field piece painted the field piece in December. In March 1940, the Post requested permission from the Mayor to erect a flagpole at that location. In September 1942 the War Production Board requested the Post sell the field piece and turn it into scrap to help in the drive for old scrap iron. The membership voted to give the field piece to the authorities at Fort Belvoir if they would haul it away. In 1950 another gun was requested. The gun was the three inch gun currently at the Memorial.
