What military types are there?

Military types can typically be classified into several categories, including active duty, reserve, and National Guard forces. Active duty members serve full-time and are permanently stationed in military roles, while reserve forces consist of individuals who train part-time and can be called to active duty when needed. National Guard units serve both state and federal missions, often responding to local emergencies as well as overseas deployments. Additionally, military branches such as the Army, Navy, Air Force, Marine Corps, and Coast Guard each have specific roles and responsibilities.
