The wavy chevron represents the Vesle River, and the five charges thereon, the five major engagements that the parent organization saw in service during World War I. The broken wheel is representative of the ten ambulances of the 103d Sanitary Train disabled while crossing the Andre Bridge over the Vesle River at Fismes, 10-13 August 1918. The aerial bomb represents the bombs dropped within a few feet of the 112th Field Hospital at Cohan, France, on the night of 12 August 1918. The yucca represents service on the Mexican Border by the 103d Medical Regiment.
CrestThe crest is that of the Pennsylvania Army National Guard.
