MEDICAL AID AND SUPPORT.
Maroon and white are colors traditionally associated with the Medical Corps. The column with the serpent entwined represents the strong medical support supplied by the unit. The stars allude to provision of command administrative duties. The octagon refers to the many phases of medical control and planning. The one column, six stars, and eight sides of the device allude to the numerical designation of the 168th Medical Battalion.
World War II campaign participation in Northern France and Normandy is recalled respectively by the fleur-de-lis and lion, the last being derived from the arms of that region. Campaigns in Central Europe and the Rhineland are represented by the ragged staff; the serpent refers to the mission of medical care and support to American troops in combat. The wreath of laurel signifies honor and achievement. Green denotes hygiene and growth, gold indicates excellence.
The coat of arms was approved on 14 September 1993. It was amended to include a crest on 3 October 2002.
