Insignia Description
A gold color metal and enamel device 1 3/16 inches (3.02cm) in height overall consisting of a gold semicircular scroll bearing the words "PER VIGILANTIAM SCIENTA" in blue letters and containing upright between two green laurel branches a gold helmet facing front with blue rivet holes around the neck and a blue grill opening, the throat encircled by a collar of checkered white and black edged gold and atop the helmet a gold three-pointed coronet, the center point in blue.

Symbolism
Teutonic helmet with crown is an allusion to Camp King in Oberursel, Germany, and its front facing position suggests alertness and vigilance. The laurel branches on either side are symbolic of honor and achievement. In the collar the colors black and white denote the two types of intelligence collection provided by the unit and the repetition of the pattern indicates the overall coverage of Europe.

History
The distinctive unit insignia was originally approved for the 513th Military Intelligence Group on 23 Jul 1968. On 20 Nov 1986 the insignia was redesignated for the 513th Military Intelligence Brigade.
