The 299th Cavalry Regiment, formerly the 299th Infantry Regiment, nicknamed the "The Koa Regiment",[citation needed] is a unit of the Hawaii Army National Guard. It was established in 1923 from the old 2nd Hawaiian Infantry Regiment, and it served during World War II as part of the 24th Infantry Division. The name "Koa" comes from the Hawaiian word for "Warrior", and is currently headquartered in Hilo, Hawaii. The 1st and 2nd Battalions, 299th Infantry were federally activated in 1968 to support the United States Army Pacific during the Vietnam War. More recently a battalion of the regiment deployed to Iraq as the 2–299th IN and again after being re-flagged in 2006 as the 1st Squadron, 299th Cavalry Regiment.[citation needed]
