About this Unit
The Army National Guard of Hawaii (HIARNG) traces its origins to the late 19th century, when local militia units were formed during the Kingdom of Hawaii era. Following annexation by the United States in 1898, these units were reorganized into the Hawaii National Guard in 1899. Throughout World War II, the HIARNG played a critical home defense role, especially during and after the attack on Pearl Harbor in 1941. In recent decades, HIARNG units have served both in state emergencies—such as natural disasters—and overseas deployments, supporting operations in Iraq, Afghanistan, and throughout the Indo-Pacific.
