The patch, a turquoise circle bordered in black, dominantly portrays the "Grim Reaper." He has a gray and white skull and hands and wears a black cloak. He holds the gold Roman numeral "XXXI" by a chain in his right hand and a scythe in his left.
The "Grim Reaper" represents the reality of death and serves to remind cadets they have, as members of the Armed Forces, devoted their lives to their country. This dedication distinguishes the military profession from all others.
This second patch of the squadron was approved in 1972.
