Banana Wars is the term used by some historians since it was coined in 1983 to refer to the occupations, police actions, and interventions on the part of the United States in Central America and the Caribbean between the end of the Spanish–American War in 1898 and the inception of the Good Neighbor Policy in 1934. These military interventions were most often carried out by the United States Marine Corps, which developed a manual, The Strategy and Tactics of Small Wars (1921) based on its experiences. On occasion, the Navy provided gunfire support and Army troops were also used.
