[2012.11.12 - 14] Info: “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!!”

[EXPLANATION]
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.
