men joined the crews. The Armed Guard served on Allied merchant marine ships in every theatre of the war. Initially, a shortage of trained officers found chiefs and even petty officers in command; later a single commissioned officer would be in charge.
Duty
The assignment as an Armed Guardsman was often dreaded because of the constant danger. Merchant ships were slow, unwieldy, and because of their lack of armor, firepower, and the important cargoes they carried, priority targets of submarines and planes. Furthermore, merchant ships were among the last to receive updated equipment. Early on in the war, some ships only had a few machine guns, so the crews painted telephone poles to imitate the barrels of larger guns. The most common armament mounted on merchant ships were the MK II 20mm Oerlikon autocannon and the 3"/50, 4"/50, and 5"/38
The Mark 12 5"/38-caliber gun was a United States dual-purpose naval gun, but also installed in single-purpose mounts on a handful of ships. The 38-caliber barrel was a mid-length compromise between the previous United States standard 5"/51 low ...

When practicable, the Navy Armed Guard aboard a merchant ship would provide cross-training to merchant crew members in the use of the guns in the event of casualties. The Navy Armed Guardsmen would typically sail round trip on the same ship, occasionally they would get a different assignment upon reaching their destination depending on Allied convoy
