1 Signal Brigade
Shoulder Sleeve Insignia
On a shield 2 1/4 inches in width overall divided into three vertical stripes orange, blue and orange, the blue center stripe 1 inch in width and surmounted by an unsheathed sword, point to top, the hilt yellow and the blade forming a bolt of lightning all within a yellow 1/8 inch border.
The orange field of the shield and the yellow border were suggested by the authorized shoulder sleeve insignia of the Strategic Communications Command of which the 1st Signal Brigade is a part. The lightning bolt, which also appear on the Strategic Communications Command shoulder sleeve insignia, is depicted on the distinctive insignia (badge) of the 1st Signal Brigade. In this instance, the lightning bolt, a symbol of communication, has been used as a sword blade and attached to a hilt, the sword thus referring to both the tactical and support mission of the organization. The blue vertical stripe with "sword" (suggested by the authorized shoulder sleeve insignia for the United States Army, Vietnam) alludes to the unit?s numerical designation.
The insignia was approved on 5 Oct 66.
Distinctive Unit Insignia
A silver color metal and enamel device 1 1/4 inches in height overall consisting of a silver barbed arrowhead, the tip conjoined with orange enamel flames issuing at base from each side of arrowhead, a lightning bolt superimposed in black enamel.
The one bolt of lightning alludes to communications and to the numerical designation (one) of the organization. The barbed arrowhead with superimposed lightning bolt refers to both the tactical and strategic support mission of the organization. The flames allude to fire being the oldest source of signal communication at a distance and thus the first, the orange "fire by night" and the black "smoke by day."
The insignia was approved on 31 Aug 66.
