Henry Harley "Hap" Arnold (June 25, 1886 – January 15, 1950) was an American general officer holding the grades of General of the Army and General of the Air Force.
 Arnold was an aviation pioneer, Chief of the Air Corps (1938–1941), Commanding General of the U.S. Army Air Forces, the only U.S. Air Force general to hold five-star rank, and the only officer to hold a five-star rank in two different U.S. military services.

 He began his military career during World War 1, enlisting in the Aviation Section of the Army's Signal Corps in 1918.
 He remained in the Reserve Corps after the war, and in 1926, became Commander, 27th Pursuit Squadron, 1st Pursuit Group.
 In 1940, Georgia Governor Ed Rivers commissioned him to form the first flying unit of the Georgia Air National Guard.
 The unit was mobilized into the U.S. Army in September, 1941, with Major Finch as commander.
 After World War II, he was a leading critic of efforts to eliminate the air arm of the National Guard during peacetime.
 General Finch gained the respect and admiration of Air National Guardsmen throughout the nation with his steadfast support and successful efforts to preserve the Air Guard.
 He became the first Chief of the Air Force Division of the National Guard Bureau in 1948.
 Under his leadership, the Air National Guard built to combat readiness and was among the first components called into service after the outbreak of the Korean War.
 As a result of General Finch's vision and perseverance, 45,000 highly trained officers and airmen of 22 wings and 65 squadrons gave the Air Force the strength it needed in the early, critical phases of the Communist drive down the Korean peninsula.General Finch served as the senior Air Force member of the United Nations negotiating team at the peace talks at Panmunjom, Korea, and received the Legion of Merit for outstanding service in 1955; General Finch assumed command of Fourteenth Air Force, Robins AFB, Georgia, becoming the nation's first Air National Guardsman to head a numbered air force.

 He also established and endowed the General John P. McConnell Award at the United States Air Force Academy.
 Considered by many as the father of the strong, independent Air National Guard existing today, General Finch retired in 1957.

 A Reserve officer in the United States Army Air Corps, Doolittle was recalled to active duty during World War II.
 He was awarded the Medal of Honor for personal valor and leadership as commander of the Doolittle Raid, a bold long-range retaliatory air raid on the Japanese main islands, on 18 April 1942, four months after the Attack on Pearl Harbor.

The North American Aviation T-6 Texan is an American single-engined advanced trainer aircraft used to train pilots of the United States Army Air Forces (USAAF), United States Navy, Royal Air Force, and other air forces of the British Commonwealth during World War II and into the 1970s.
 Designed by North American Aviation, the T-6 is known by a variety of designations depending on the model and operating air force.
 The United States Army Air Corps (USAAC) and USAAF designated it as the AT-6, the United States Navy the SNJ, and British Commonwealth air forces the Harvard, the name by which it is best known outside of the US.
 Starting in 1948, the new United States Air Force (USAF) designated it the T-6, with the USN following in 1962.
 It remains a popular warbird aircraft used for airshow demonstrations and static displays.
 It has also been used many times to simulate various Japanese aircraft, including the Mitsubishi A6M Zero in movies depicting World War II in the Pacific.

A Reserve Good Conduct Medal refers to any one of the five military conduct awards which are issued by the United States Armed Forces to enlisted members of the Reserve and National Guard.
 The primary difference between the regular Good Conduct Medal and the Reserve Good Conduct Medal is that the Good Conduct Medal is only issued for active duty service while the reserve equivalent is bestowed for reserve duties such as drills, annual training, and additional active duty for either training or operational support to the active duty force or, in the case of the Army National Guard and Air National Guard, in support of Title 32 U.S.C. state active duty (SAD) such as disaster response and relief.
 To receive a Reserve Good Conduct Medal, a service member (excluding Army Reservists), must, generally, be an active member of the Reserve or National Guard and must have performed three to four years of satisfactory duty (to include drills and annual training) with such service being free of disciplinary action.
 Periods of active duty in the Active Component prior to joining the Reserve Component, full-time duty in an Active Guard and Reserve, Training and Administration of the Reserve (TAR), Full Time Support (FTS), or active duty recall or mobilization in excess of three years are not typically creditable towards the Reserve Good Conduct Medal, although such periods are typically creditable for the active duty equivalent Good Conduct Medal.
 Each service has specific varying requirements.
The Air Force Longevity Service Award is a military award of the United States Air Force established by Air Force General Order 60, on 25 November 1957 by General Thomas D. White, Air Force Chief of Staff.
 The award was primarily created as an Air Force equivalent to the service stripes used by other branches of the United States military to denote years of military service.
 The award is retroactive to the establishment of the U.S. Air Force as an independent service in September 1947.
 The ribbon is also retroactive for any service with the U.S. Army Air Forces, U.S. Army Air Corps, or U.S. Army Air Service prior to the creation of the U.S. Air Force as a separate service as long as the serviceman was on Active Duty on or after 18 September 1947.
