The Vietnam War

Although many soldiers and officers from the Maine Army National Guard served as volunteers in Vietnam or South East Asia, none of Maine's units were called into service.

Major changes came to Maine's force structure between 1959-1961. The 103rd Infantry Regiment converted from infantry to armored cavalry, and then to armor. The field artillery transitioned from towed howitzers to self-propelled guns. The anti-aircraft battalion transitioned to the 262nd Engineer Battalion.

In 1964, the strength of the Maine Army National Guard was 2,641 personnel in the following units.
