Failed the Exam: I Became a Mercenary!

Question: Is it possible to become a mercenary after failing the exam due to a cold in high school? "What? No!" "Then my three thousand dead soldiers are enough!" "Not enough!" "What, it's not enough! I'll give you an AK, I'll give you a tank! If it doesn't work, I'll give you a JAS-39 Gripen fighter, okay?" "What happens after that?" "Let's make it bigger and stronger and spread the glory!" "Then fuck him!" High school classmate: "Damn it, you're such a good guy, we're going to praise you for being such a good guy!"
