we could wear our own rigs thankfully, since 10 mags is a must and our issue rigs aren't really suited for access to more then 4 quickly, my c-9 gunners used their old style web gear to carry their ammo, cuz again the new vest is not ideal for a c-9 gunner
very early on our tour we were told if we had done anything to our weapons to have a tech sign off on it, so we all went and had them inspected even if it was just a forward grip etc. everyones bum was then covered, C o C was happy, we were happy, guns were happy and painted and tricked out
the elcan worked fine, some scopes are needed even in close TIC's cuz timmy taliban likes to mousehole and this often hid his weapon signature, but dude with a scope could find him now and then, a sprinkling of eotech's and other same type sights is great too cuz some TIC's at 25-50m require fast target acquisition
