Description
On a rectangular shield arced at top and base 2 3/8 inches (6.03 cm) in width and 3 1/8 inches (7.94 cm) in height overall, quartered gray and blue, a bottony cross 2 inches (5.08 cm) in width and 2 inches (5.08 cm) in height overall quartered red and white, and surmounted diagonally overall by a yellow bayonet (of the period of the War Between the States), the point in upper left, all within a 1/8 inch (.32 cm) white border.

Symbolism
The blue and white are Infantry colors, the original unit designation. The red and white quartered bottony cross is taken from the shield of the coat of arms of Lord Baltimore and appears on the state flag and state seal of Maryland. The blue and gray represents the service of Maryland’s units in the 29th (“Blue and Gray”) Infantry Division in World War I and World War II. The bayonet represents the achievements of the Maryland Line during the War for Independence and the gallantry of the “Maryland 400” at the Battle of Long Island, August 1776, the first recorded use of the bayonet by American soldiers.

Background
The shoulder sleeve insignia was originally approved for the 58th Infantry Brigade on 17 September 1976. The insignia was rescinded on 1 July 1988, when the brigade became a divisional brigade and was no longer a separate brigade. It was reinstated and redesignated for the 58th Infantry Brigade Combat Team with the description and symbolism updated on 1 June 2006. It was redesignated effective 1 September 2010, for the 58th Battlefield Surveillance Brigade with the symbolism updated. (TIOH Dwg. No. A-1-598)
