Hi , I also serving my NS in police force but I can't reveal
which Intake i am from but I can share with you my life in
PA.
When you go to the Police academy , you will go to a hall where you
can see a lot of NS men waiting there. Then following you will see
your FI & your OC leading your squad to your barrack (which is
neither Alpha , Bravo , Delta or Charlie Coy) If you are a smoker ,
be smart & keep your cigarettes well. You can bring your HP
battery along. Don't ever declare this two items to your FI. You
can almost buy instant noodles in after book out... Advice: Keep
well too
Your FI will be very demanding & strict at the first few months
but after that , he will be a close friend to you 
Anymore questions to ask
