The red and yellow flash connotes the prominent role of electronic signals intelligence in modern warfare. The Cavalry saber, flash and quartered field, collectively suggest the blending of the traditional with the latest modern developments in intelligence, reconnaissance, security and electronic warfare capabilities within the Battalion.
