I served 25 years ago and I had completed my long reservist cycle. We had rifle PT, log PT, long runs and drills and tough physical training in the field under the hot sun etc.. but those were within regulations.
The officers and NCOs in my active unit and my reservist unit all know the golden rule of SAF, to follow always regulations to cover backside. it's not worth getting into shit for breaking regulations, especially for regulars as it could affect their ricebowl and career. NS slaves just want to serve their time peacefully and fuck off, it's not worth ruining your life getting seriously injured or die in NS, and the fucking compensation is so pathetic.
