Members of the United Nations Command Security Battalion/Joint Security Area (UNSCB/JSA), eat lunch and check email while on duty at Observation Post Oullette (OPO). In the event of an alarm, the platoon drops what they are doing and man their posts in a matter of seconds. The platoon practices alert procedures every day during the day and night. After being alerted the platoon heads to a central point where gear is gathered and orders for which bunker to man are given
