In the Army, squads are made up of up to a dozen people. Squads can be combined to form a platoon, which consist of 20 to 40 soldiers. Put three to five platoons together, and you’ve got a company.
According to jungsoo's dad, if there is one line above the circle on the yellow band, he is a "platoon leader". But if there are 2 lines, he is a "company leader"!
Jungsoo's yellow band has 2 lines!! T______T SO PROUD OF HIM
