Metallic silver and white refer to perfection, a characteristic the cadets reflect in the high standards they have for themselves. Blue reflects loyalty, a virtue the cadets possess for each other and their country. The falcon (the school's mascot) is symbolic of freedom and victory. The ionic column alludes to fortitude and strength. The palm leaves suggest victory and commemorate Florida's state tree; the palm tree.
