We wore army pants and boots during our trekking in Taman Negara after the SPM exams. For nothing kena tahan by a group of army patrolling near there. Got lectured like nobody business.
They told us not to wear these types of clothes as they are not aware of any other teams patrolling near their area and they will consider us as 'threats' - in other meaning, they can shoot us if necessary

Actually if there wasnt a lady teacher with us, I think most probably they will think were communists. Just imagine - army uniform complete with backpack

In this condition, when 2 groups suddenly face each other out of nowhere, sure will panic one.We also almost ran away when saw them with weapons.
We were wearing our kadet uniform - you know during schooling time (Pasukan Berseragam Kadet) the patchy green color one.
