To do this kinda operation....wisdom tooth, circumcision,
operation....etc.
You need approval from SAF.
Reason being very simple, the Army is depending on everyone to be
available 24/7 for operations, you can't just decide to do it, and
leave them with "no choice" but to release u.
If you really go ahead and do it, fine, they will give u MC cause u
really can't turn up...but u'll be charged after that for breaking
the laws of SAF of not seeking prior approval, failure to comply
with lawful orders, etc. etc.
Don't play punk and think SAF got "no choice", u'll get it.
