Duties

National Guard units can be mobilized at any time by presidential order to supplement regular armed forces, and upon declaration of a state of emergency by the governor of the state in which they serve. Unlike Army Reserve members, National Guard members cannot be mobilized individually (except through voluntary transfers and Temporary DutY Assignments TDY), but only as part of their respective units. However, there has been a significant number of individual activations to support military operations (2001-?); the legality of this policy is a major issue within the National Guard.^{[citation needed]}

Active Duty Callups

For much of the final decades of the twentieth century, National Guard personnel typically served "One weekend a month, two weeks a year", with a portion working for the Guard in a full-time capacity. The current forces formation plans of the US Army call for the typical National Guard unit (or national guardsman) to serve one year of active duty for every three years of service. More specifically, current Department of Defense policy is that no guardsman will be involuntarily activated for a total of more than 24 months (cumulative) in one six-year enlistment period (this policy is due to change 1 August 2007, the new policy states that soldiers will be given 24 months between deployments of no more than 24 months, individual states have differing policies).

History

This section needs expansion. You can help by adding missing information. (June 2008)

Kingdom

The earliest forerunner of the Hawaii Army National Guard was the Honolulu Rifles a militia formed in 1854.^{[citation needed]} In 1887 it was certified as a paramilitary.^{[by whom?]}

Republic

On January 27, 1893, following the Overthrow of the Hawaiian Kingdom, the National Guard of Hawaii was formed largely adopting men from the Honolulu Rifles.^[7] The first action as a national guard was during the Leper War a pyyrhic victory.

Territory

On August 12, 1898 National Guard of Hawaii was converted into the Hawaii National Guard. In 1938 members of the 2nd BN, 299 INF RGT of the Hawaii National Guard unit in Hilo aided striking workers against government authorities during the protest that became known as the Hilo Massacre. In 1940, with the 298th INF RGT and 299th INF RGT of the Hawaii National Guard being federalized, the governor and Adjutant General had minimal troops available to carry out Territorial duties.

After the attack on Pearl Harbor, the Hawaii Territorial Guard was created to serve as the stateside replacement for the National Guard. As a State Defense Force, the Hawaii Territorial Guard was not subject to federalization or deployment, but rather answered only to the governor. In January 1942, due to suspicions of their loyalty, Hawaii Territorial Guardsman of Japanese ancestry were dismissed. However, the Japanese members of the Hawaii National Guard who were on Active Duty with the 298th and 299th INF RGTs were retained until June 1942, when they were removed and placed in the Hawaiian Provisional Battalion. This unit would soon become the famed 100th Infantry Battalion.

Historic units

298th Infantry Regiment - The 298th Infantry was organized as the 1st Regiment, National Guard of Hawaii from 1893-95 at Honolulu. It was redesignated as the 1st Hawaiian Infantry Regiment and mobilized into federal service during World War I at Fort Shafter, Hawaii from 1918-19. In 1923 it was redesignated as the 298th Infantry Regiment. Called to Federal service on 15 October 1940, the 298th Infantry was assigned to the 25th Division on 1 October 1941. On 7 December 1941 the 298th Infantry came under fire and took casualties during the Japanese attack on Pearl Harbor. On 23 July 1942 the 298th Regiment was reassigned to the 24th Infantry Division. On 12 June 1943 the 298th Infantry was relieved from assignment to the 24th Division and was designated as a separate infantry regiment. It was assigned to the U.S. Army Central Pacific and participated in the Central and Western Pacific, Leyte and Ryukyu campaigns. The regiment was released from federal service on 10 April 1945 in Hawaii. On 8 January 1957 the 298th Infantry was reorganized and redesignated as the 298th Antiaircraft Artillery Group. It was further redesignated as the 298th Artillery Group (Air Defense) on 15 November 1961. On 22 January 1972 the 298th was reorganized and redesignated as the 298th Field Depot with station at Wahiawa, Hawaii. On 1 June 1976 the 298th Field Depot was inactivated with its headquarters and headquarters company being consolidated with headquarters and headquarters detachment, Hawaii Army National Guard. On 16 August 1997, a new 298th Regiment not related by lineage to the original 298th Infantry Regiment, was constituted as a Regional Training Institute for the Hawaii Army National Guard at Waimanalo, Hawaii. During COVID-19, the Medical Detachment (MED DET) helped distribute vaccines, and successfully executed its Health Service Support and Force Health Protection missions, which aimed to maintain high levels of medical readiness. They conducted Periodic Health Assessments, Dental Examinations, Hearing Test, Profiles, Vision Readiness Screenings, Immunizations, Flight Physicals, Behavior Health Support, and Case Management Support.^[8]
