Exemptions for ball sports in the Asian Games are going too far

Our biggest rival in ball sports is Japan.
Korea puts forth its absolute best effort to secure military exemptions,
but Japan doesn't even send its first-string players and instead fills the roster with amateur/club players.
What's even more surprising is that even against a Japanese team composed of amateurs, we didn't win easily; it was a nail-biter that barely ended in a win.
Given this situation, I don't understand why we provide military benefits that go beyond just winning a gold medal.
