I'm at a loss here. Who do you work for/ with?
The original FSBE's were all to Force guys, with a verrrryyy few going to others for T&E.
Is yours a commercially sold vest?
For blackside the pouches are attached to the FSBE carrier.
The body armor is not normally worn for greenside, so an LBV/ LBE is worn only on top of you.
The current operation has expanded Force's role somewhat, to include vehicular patrols. The RACK is the school solution and part of Lessons Learned.
In any event, good luck with your vest- i hope it is never tested.
