The shield colors associate the three schools affiliated with the Minnesota State University ROTC program (Minnesota State University, Gustavus Adolphus College and Bethany Lutheran College). The wavy partition line alludes to the schools location in Mankato, at the junction of the Minnesota and Blue Earth Rivers. The lamp, cross and crowns are symbolic of the cadets of each of the schools and their joint dedication to support their schools, communities and country.
