The Royal Thai Armed Forces were involved in many conflicts throughout its history, including global, regional and internal conflicts. However, most these were within Southeast Asia. The only three foreign incursions into Thai territory were the Franco-Siamese War, the Japanese invasion of Thailand in December 1941, and in the 1980s with Vietnamese incursions into Thailand that led to several battles with the Thai Army. Operations on foreign territory were either territorial wars (such as the Laos Civil War) or conflicts mandated by the United Nations.
