A Silver color metal and enamel device 1 3/16 inches (3.02 cm) in height overall consisting of a shield blazoned: Per chevron abase Azure and Argent (Silver Gray), a doubled-headed wrench and airplane propeller in saltire Or and in base a stylized vortex Tenn. Attached below a bi-partite Blue scroll inscribed CONSERVARE LIBERTATEM" in Silver.
Ultramarine blue and golden orange are the colors traditionally associated with Aviation units. The gold crossed wrench and propeller represent the 1108th Aviation Group's mission of aviation maintenance for both fixed and rotary wing aircraft. The nebule denotes the sky. The stylized orange vortex alludes to Hurricane Katrina that struck the unit's home station of Gulfport, Mississippi, on 29 August 2005, severely damaging or destroying more than 75% of the Soldier's homes. The image serves as a reminder that following the unit's immediate release from active federal service, the Group continued to serve on Title 32 for more than 45 days as part of the overall Hurricane Katrina response effort in Mississippi. The motto translates to "Maintaining Freedom."
The distinctive unit insignia was approved on 19 December 2012.
