Heraldry

In the early 1960s, the 121st Tactical Fighter Squadron developed and approved a fuselage insignia, an iron fist and jet fighter superimposed on a national shield. It was thought that the unit had no previous insignia, but the designers were incorrect. A Maryland Terrapin originally flew with the District of Columbia Air National Guard and, many years later, was reinstated as the unit's insignia. The original design, approved in 1943, and authenticated as correct by the Air Museum, Wright-Patterson Air Force Base, is described as follows. "A caricatured tan and brown turtle proper , riding a "pogo" stick, leaving a trail of hops and impact marks black, all outlined light turquoise blue. Significance: The turtle depicts slow but sure travel, as characterized by the story of the "Tortoise and the Hare" in "Aesop's Fables." The short hops and limited range of liaison airplanes are depicted by the short hops the turtle is making on the pogo stick."

, along with southern Maryland and northern Virginia. Parts were no problem and many of the maintenance personnel were World War II veterans so readiness was quite high and the planes were often much better maintained than their USAF counterparts. In some ways, the postwar Air National Guard was almost like a flying country club and a pilot could often show up at the field, check out an aircraft and go flying. However, the unit also had regular military exercises that kept up proficiency and in gunnery and bombing contests they would often score at least as well or better than active-duty USAF units, given the fact that most ANG pilots were World War II combat veterans. In December 1949 the 121st Fighter Squadron converted from its P-47s to F-84C Thunderjets as the first Air National Guard squadron to be equipped with jet aircraft.

In the air defense role these models lacked any BVR capability, limiting them only to close range combat with their gun and Sidewinder missiles. In the attack role these aircraft were able to deploy bombs, but with their smaller stabs the center of gravity of these aircraft was far from ideal making it quite a challenge for the pilots to fly these missions.

Instead of entire permanent units deploying as "Provisional" as in the 1991 Gulf War, Expeditionary units are composed of "aviation packages" from several wings, including active-duty Air Force, the Air Force Reserve Command and the Air National Guard, would be married together to carry out the assigned deployment rotation.

Finally, when the Cessna came within three miles of the White House – just a few minutes flying time – it altered course. In its 2005 BRAC Recommendations, the DoD recommended that
