This auction for a Triple Aught Design Control Panel 1 in OD green. It has Molle / Pal webbing and is designed to be able to tie items like pouches (or holsters and gear) to the inside of the pack. Specifically made with the Fast Pack in mind, the two straps on top are used to fasten it to the inside of the pack.
This was very seldom used in a range bag, like new condition.
I have a lot of related TAD gear on auction (Fast Pack Litespeed, extra transporter tail, OP1, GPP2, RDDP1, stability belt etc.). Possibility of reduced price and combined shipping if you take more items.
