For its Distinctive Unit Insignia, colloquially known as a Unit Crest, the 1st Medical Brigade features a maroon shield with silver oak leaves encompassing an esquire’s helmet emblazoned with the red numeral “1”—the shoulder-sleeve insignia of the 1st Infantry Division, with whom the unit served in World War I. A silver scroll bears the unit’s motto, “Fortitude and Compassion,” in black letters. This striking design bears very little in common with the 1st Medical Brigade's CSIB.
