Vice Chief of the National Guard Bureau: The Vice Chief of the National Guard Bureau (VCNGB) is the second highest-ranking officer of the National Guard Bureau, which is a joint activity of the United States Department of Defense.  The Vice Chief of the National Guard Bureau is the second in charge of the National Guard of the United States; which is a joint reserve component of the United States Army and the United States Air Force.  The VCNGB serves as the principal advisor to the Chief of the National Guard Bureau and the Secretary of Defense, through the Chairman of the Joint Chiefs of Staff, on matters involving non-federalized National Guard forces and on other matters as determined by the United States Secretary of Defense.  The VCNGB also serves as the principal adviser to the Secretary of the Army, Secretary of the Air Force, the Chief of Staff of the Army, and the Chief of Staff of the Air Force, on matters relating to federalized forces of the National Guard of the United States and its subcomponents; the Army National Guard of the United States, and the Air National Guard of the United States.

4700th Air Defense Group: The 4700th Air Defense Group is a discontinued United States Air Force (USAF) organization.  Its last assignment was with the 4709th Air Defense Wing at Stewart Air Force Base, New York.  It was activated in 1950 as a support unit for USAF units at Stewart.  In 1954, it assumed an operational mission and was assigned two interceptor squadrons.  The group was discontinued on 18 August 1955 and its personnel and equipment were transferred to the 329th Fighter Group (Air Defense) as part of Project Arrow, an Air Defense Command project to air defense groups with fighter units with distinguished histories from World War I or World War II.

ACEVAL/AIMVAL: The Air Combat Evaluation (ACEVAL) and the Air Intercept Missile Evaluation (AIMVAL) were two back-to-back Joint Test & Evaluations chartered by the United States Department of Defense that ran from 1974-78 at Nellis Air Force Base in Nevada.  Both the U. S. Air Force and Navy participated, contributing a team of F-15 Eagle and F-14 Tomcat fighter aircraft and using the local F-5E Aggressor aircraft as the Red Force.  The fundamental question that needed to be answered was one of "quantity vs quality".  Mock engagements showed that cheaper, lower-technology fighters armed with all-aspect missiles were able to destroy the more advanced, expensive F-15's and F-14's.  These results of the AIMVAL/ACEVAL testing led to the Air Force decision to structure its fighter forces with a balance of cheaper F-16's along with the more expensive F-15's, and the Navy took a similar strategy in procuring cheaper F-18's along with the more expensive F-14's.  The results had other impacts as well, such as decisions regarding missile development.

Patrick Air Force Base: Patrick Air Force Base (IATA: COF, ICAO: KCOF, FAA LID: COF) is a United States Air Force installation located between Satellite Beach and Cocoa Beach, in Brevard County, Florida, in the United States.  It was named in honor of Major General Mason Patrick, USAAC.  An Air Force Space Command (AFSPC) base, it is home to the 45th Space Wing (45 SW).

It was originally opened and operated from 1940 to 1947 as Naval Air Station Banana River, a U.S. Navy airfield.  It was then deactivated as a naval installation in 1947 and placed in caretaker status until it was transferred to the Air Force in late 1948.

Its last assignment was with the 37th Air Division of Air Defense Command (ADC) at O'Hare International Airport (IAP), Illinois where it was discontinued in 1956.  It was established in 1952 at O'Hare as the 4706th Defense Wing in a general reorganization of Air Defense Command (ADC), which replaced wings responsible for a base with wings responsible for a geographical area.  It assumed control of several Fighter Interceptor squadrons that had been assigned to the 142d Fighter-Interceptor Wing, an Air National Guard wing mobilized for the Korean War and the 56th Fighter-Interceptor Group.  In early 1953 it also was assigned six radar squadrons in the Midwest and its dispersed fighter squadrons combined with colocated air base squadrons into air defense groups.  The wing was redesignated as an air defense wing in 1954.  It was discontinued in 1956 and most of its units transferred to the 58th Air Division.

Nellis Air Force Base: Nellis Air Force Base ("Nellis" colloq. ) is a United States Air Force installation in southern Nevada with military schools and more squadrons than any other USAF base.
