The key is adapted from the Military Intelligence regimental insignia. The embattled castle wall is for the Engineer Corps. The triangular shape alludes to the isosceles triangle, strongest structure known. The morion, a crested metal helmet worn by the Spanish soldiers of the 16th and 17th centuries, highlights Florida's exploration history. The three pellets surrounding the helmet bring to mind cannon balls and symbolize defense, combat readiness, and the teamwork of the Special Troops Battalion.
The distinctive unit insignia was approved on 17 September 2007.
