Symbolism
The colors oriental blue and silver gray (white) are used to represent Military Intelligence and scarlet and gold to symbolize military strength and operational excellence. The griffin, traditionally a creature of vision, alertness and intelligence, is shown as a chess piece adjacent to a chessboard, suggesting the type of operation, requiring ingenuity and intellect, which the battalion is called upon to carry out. The squares on the chessboard represent the many Vietnam engagements in which the battalion participated.

History
The distinctive unit insignia was approved on 22 November 1983.
