The Marcus Color Guard performs with the marching band during the fall season, but performs as its own entity in the winter and spring seasons. This activity takes place indoors, most often in the school gymnasium, and is known as "Winter Guard.

The Winter Guard prepares a production lasting usually 4-6 minutes, set to recorded music of the designer's choice. The Winter Guard activity often gives Color Guard members the opportunity to explore even more intricate forms of dance, movement, choreography, and equipment work, as the sole focus becomes anywhere from 5 to 30 members who make up a typical performing Winter Guard unit. The Marcus Winter Guard travels to its own competitions, governed primarily by one of two organizations: The North Texas Color Guard Association (NTCA) and Winter Guard International (WGI)
