Greg,
your chain seems to think they have to take everything in Bn with them into theatre. They seem to have forgotten that the Brigade has raped itself over the past 3 years to send everything into theatre. It's all there. But, they want to take a Battle Group's worth of kit over with them, even though there is more than a Battle Group's worth already there. They're killin' me.
The vests/chest rigs aren't expected until December. That was right from the manufacturer. They need 'x' amount of time to prepare the order, after receiving it. Again, your chain expected the kit to be shipped and in Bn the day after the CLS cut the order.
