As "bbbc" has already mentioned, you'll book in on Sunday
evenings & book-out on Fridays evenings BUT unless you're
unlucky enough to kena guard duty then that's a total different

As for the portion part, well mostly are malays whereby you can
spot several with tattoos, some visble whereas some aren't but as
long as you try to get along with each other, I'm sure you'll enjoy
your recruit life
