 The Four Corners is a joint partnership between the Four of the Four of First, Army Field Support Brigade, and Third Sustainable Brigade. What it allows the unit to do is wait until the last tactical minute or their last combat or their last patrol with Corps coming in and have them at one stop shop, one single location that they can turn in all their classes of supply. Take everything that they've received over here and turn it all in in about two hours. We have our trans experts, we have our ammo abatement team all in one single location ready to support the warfighter. Checking for brass and ammo on these strikers. It tends to roll down and bounce around the body line so they find interesting places to hide. Without the ability for a Four Corners what would happen is each separate class of supply they would have to go to a different yard, a different location, a different unit and turn it in. So they'd have to schedule appointments because each unit is busy doing their own mission and we have all the subject matter experts, all the units they turn into in one single location. We're just doing this so we can get that ammo cleared so they can get out of here and get home and we can get this ammo turned back in and get new ammo or get it ready to get moved out of Afghanistan. It's a unique logistics problem and every day that we get to wake up it's how can we support, how can we retrograde, how can we redistribute this. The most cost-effective, the simplest and the easiest way. And I think being able to do that mission really is a sense of pride that we're doing a good job that we're doing such support and we're getting so much done.
