WCPolaroids: Zero (3/11)

Mister 45-degree strikes again. Well, lets take a look at Zero's insignias. The two gold squares over his left breast pocket are his rank and service -- signifying, in this case, that he is a 1st Lt in the Space Forces. The trapezoid pin on his right breast pocket are his wings, earned for having passed through Advanced Flight School. Anyone have any theories as to what the triangle pins on his collar are?
