On a scarlet disc with a 1/8 inch (.32cm) yellow border 2 1/2 inches (6.35cm) in diameter overall, a yellow sun emitting twelve rays surmounted by a blue horizontal wavy band bearing a yellow gliding snake.
The wavy band and the snake are taken from the coat of arms of the former organization, the 116th Armored Cavalry Regiment. The wavy band and snake represent the Snake River, and refer to the home area of the former organization, the Snake River Valley. The sun alludes to the state of Idaho, noted for the beauty of its sunrises. The name is taken from Shoshoni Indian words meaning " the sun comes down the mountain" or "it is morning." The predominant color, yellow, is representative of Armored Cavalry units.
The shoulder sleeve insignia was originally approved for the 116th Armored Cavalry Regiment on 9 October 1967. It was redesignated for the 116th Cavalry Brigade, effective 1 September 1989, with the symbolism revised. (TIOH Drawing Number A-1-468)
