DISTINCTIVE UNIT INSIGNIA

• Description: A gold color metal and enamel device that consists of a gold eagle grasping a horizontal baton from which is suspended a red signal flag with a white center, enclosing the flag from a star at the bottom, a wreath of laurel all gold and at top left and right a white scroll inscribed PRO PATRIA at left and VIGILANS at right in gold.

• Symbolism:

1. The gold eagle holds in his talons a golden baton, from which descends a signal flag.
2. The design originated in 1865 from a meet¬ing of Signal Corps officers, led by Major Albert J. Myer, the chief signal officer, in Washington, D.C.
3. The badge was a symbol of faithful service and good fellowship for those who served together in war and was called the Order of the Signal Corps.
4. The motto PRO PATRIA VIGILANS (Watchful for the Country) was adopted from the Signal School insignia and serves to portray the cohesiveness of Signal soldiers and their affiliation with their regimental home.
5. The laurel wreath depicts the myriad of achievements through strength made by the Corps since its inception.
6. The battle star centered on the wreath represents formal recognition for participation in combat. It adorned a signal flag and was first awarded to Signal Corps soldiers in 1862. The battle star typifies the close operational relationship between the combined arms and the Signal Corps.
