The Distinctive Unit Insignia (unit crest) for the 30th Medical Brigade was redesignated for the 30th Medical Brigade on October 16, 2013. The Maroon on the shield and white on the sword are the colors traditionally associated with the Medical Corps. The blades of the sword and daggers themselves designate the unit as a military organization, and the serpent references the Staff of Aesculapius, which represents the unit's medical heritage. The star in the mouth of the serpent denotes Texas, its state of origination. The motto, "In Cruce Mea Fides" means “In The Cross Is My Faith”, is expressive of the confidence placed in the medical functioning of the original organization.
And the design of the unit crest has seen almost as many changes as the designation of the unit itself. Originally approved for the 30th Medical Regiment on February 10, 1943. It was amended to correct the description on June 26, 1943. It was subsequently rescinded in 1959, but then reinstated and redesignated for the 30th Medical Group on June 16, 1966. The description and symbolism both were revised and redesignated for the 30th Medical Brigade on December 10, 1993. That was the last revision, but it was redesignated twice more: Once as a command and finally as the 30th Medical Brigade on October 16, 2013.
As of Winter 2024, the 30th Medical Brigade remains an active unit in the U.S. Army. It is assigned to the 21st Theater Sustainment Command, United States Army Europe and is stationed at Sembach Kaserne in southwest Germany.

Distinctive Unit Insignias are worn by all Soldiers (except General Officers) in units that have been authorized to be issued the device. It is worn centered on the shoulder loops of the Army Green Service Uniform (AGSU) and the blue Army Service Uniform (ASU, Enlisted only) with the base of the insignia toward the outside shoulder seam. Current regulations do not permit the DUI to be worn on the Dress variations of either uniform, however.
More guidance on wear of the DUI is found in DA Pamphlet 670-1, Section 21-22, "Distinctive unit insignia" and 21–3(d) and (e), "Beret" and "Garrison Cap," respectively. Related Items30th Medical Brigade Patch (SSI)
