Leon,
Have you ever served at Bastion?
If so you'll know all about the 'hat police', 'high viz police' and 'gun police' - not forgetting of course 'the correct sunglasses with correct lens police'. In effect, if there's a chance you're out and about between dusk/dawn you are mandated to wear a high viz part of clothing to minimise the risk of being mown down by a caffeine or heroin doused driver (depending on nationality).
Never mind that enforcing all these rules (mostly petty...) provide gainful full-time employment for several detached personnel.....
Depending on the length of visit you don't need to be armed; the S/L behind CAS is wearing a thigh holster and the F/L probably has a hip holster. That ramp is waaay out of range of sniper fire from outside camp.
