17 September 1958 - Unknown.

The design is that of the distinctive insignia
for the unit. The triangle is the symbol for the
Greek letter delta and refers to Big Delta, the
airfield used during World War II for ferrying
troops to Russia. Inside the triangle is an
abstract interpretation of Mount Hays, the dominant
feature in this area. The mountain and the snow at its
base indicate the cold weather and mountain operations
of the unit. The inscription, translated from the Latin,
reads "We battle cold and conquer mountains."
