Insignia
The squadron insignia, the ace of spades with a dagger driven through the center of the card scripted "Caveat hostis," Latin for "Let the enemy beware," was approved on 18 July 1931 by the War Department and is still in use today. One of the original sheet metal hand painted insignia from the fuselage of a Consolidated O-17 Courier can still be seen today in the squadron commander’s office. Current Air Force heraldry regulations require squadron emblems include circular background; however, the 116th's patch as worn today by its members is the ace and dagger with no circle.
