"Deuce"
1955
The patch is a large circular emblem with a thin silver
border. A banner inscribed with the word "DEUCE" sits on top of
the circle. From a white contrail on a black field emerges the
Roman numeral II. A red and blue contrail, produced by two jet
aircraft frame the white contrail.
The red, white and blue contrails represents the colors of
the American flag. The "II" identifies the Second Cadet
Squadron. The black background signifies the vastness of space.
The planes originating from the top of the field denote
humanity’s conquest of space. The three contrails represent the
three areas in which all cadets strive to excel: Military,
academics, and athletics.
This patch, designed and first used by the Second Cadet
Squadron in 1972, is the third patch worn by its members.
