The 396th Bombardment Group is an inactive United States Air Force unit.
 It was last assigned to the Third Air Force, being stationed at Drew Field, Florida.
 It was inactivated on 1 May 1944.

The Nellis Air Force Base Complex (Nellis AFB complex, NAFB Complex ) is the southern Nevada military region of federal facilities and lands, e.g., currently and formerly used for military and associated testing and training such as Atomic Energy Commission atmospheric nuclear detonations of the Cold War.
 The largest land area of the complex is the Nevada Test and Training Range, and numerous Formerly Used Defense Sites remain federal lands of the complex.
 Most of the facilities are controlled by the United States Air Force and/or the Bureau of Land Management, and many of the controlling units are based at Creech and Nellis Air Force Bases (e.g., 98th SRSS for NTTR's southern range).
 Initiated by a 1939 military reconnaissance for a bombing range, federal acquisition began in 1940, and McCarren Field became the World War II training area's 1st of 3 Nevada World War II Army Airfields (cf. Indian Springs & Tonopah) and 10 auxiliary fields.
 The area's first military unit was initially headquartered in the Las Vegas Federal Building while the WWII Las Vegas Army Airfield buildings were constructed.
The 84th Combat Sustainment Group is an inactive United States Air Force (USAF) group last assigned to the 84th Combat Sustainment Wing at Hill Air Force Base, Utah, where it was inactivated in 2010.
 The group was formed in 1942 as the 84th Bombardment Group, one of the first dive bomber units in the United States Army Air Corps and tested the Vultee Vengeance, proving that aircraft unsuitable as a dive bomber.
 As an Operational Training Unit, it was the parent for several other bombardment groups, but from 1943 until it was disbanded in 1944, trained replacement aircrews as a Replacement Training Unit designated the 84th Fighter-Bomber Group.
The United States Air Force uniform is the standardized military attire worn by airmen of the United States Air Force.
 Specific Air Force Instructions address standardized wear that is identical for members of both the Active Component (i.e., the Regular Air Force) and that of the service's two reserve components that comprise the Air Reserve Component, that being the Air Force Reserve and the Air National Guard.
 This includes personnel in the Air Force's sole enlisted accession program, Basic Military Training (BMT), and the three USAF commissioned officer accession programs: Officer Training School (OTS) officer trainees, college/university level Air Force Reserve Officers' Training Corps (AFROTC) cadets and United States Air Force Academy (USAFA) cadets.
 Provisions are also included for authorized wear on certain occasions by honorably retired career members of the Air Force, to also include retirees of both the Air Force Reserve and the Air National Guard.

 The Group was discontinued on April 1, 1961, when Air Force Systems Command replaced Air Research and Development Command and components of its mission were distributed among other units.
The Nevada Test and Training Range (NTTR) is one of two military training areas used by the United States Air Force Warfare Center at Nellis Air Force Base in Nevada.
 The NTTR land area includes a "simulated Integrated Air Defense System", several individual ranges with 1200 targets, and 4 remote communication sites.
 The current NTTR area and the range's former areas have been used for aerial gunnery and bombing, for nuclear tests, as a proving ground and flight test area, for aircraft control and warning, and for Blue Flag, Green Flag, and Red Flag exercises.

The Utah Test and Training Range (UTTR) is a military testing and training area located in Utah's West Desert, approximately 80 mi west of Salt Lake City, Utah.
 UTTR is currently the largest contiguous block of over-land supersonic-authorized restricted airspace in the contiguous United States.
 The range, which has a footprint of 2675 mi2 of ground space and over 19000 mi2 of air space, is divided into North and South ranges.
 Interstate 80 divides the two sections of the range.
 The site is administered and maintained by the US Air Force's HQ UTTR, formerly known as the 388th Range Squadron (388RANS) stationed at Hill Air Force Base, Utah.
