I kinda work in the land of warrant officers and though I may not be a SAF regular, in my time here I have met many who have been caught in this position, I am sure they will be able to relate to it.
I kinda like the raw honesty of this film haha.
Also, "KAN NAH YOU DARE TO CALL ME BO JI, LIM PEH US RANGE AIRBORNE RANGER YOU GOT ANOT!" xD. This actually sounds very familiar heh.
