Symbolism
Scarlet and yellow are the colors traditionally associated with Field Artillery. The rayed sun, a symbol of excellence, gives the allusion of a shellburst, and also suggests the scenic wonders of Wyoming. The bucking bronco expresses the spirit, determination and heritage of the soldiers of the Wyoming Army National Guard.
