Army is like this, if cannot take it try SAF hotline, ive known a few NSF who called there actually.. begged them for post out. or just find ways chao keng and downgrade.
Either way NS is waste of time so whether you serving in combat or service stilll the same ultimately.
Combat side can make stronger bonds with ur friend and their slack is damn slack, xiong is damn xiong
but service side maybe stay out and not xiong.
