National Defense Coordinator:
Each week, the Department of Defense sends food packages to its Navy Seals training in a covert operation. The ten specially ordered shipments sent out last week were sent out on Monday. Last week, all of the shipments that were sent out on Friday consisted entirely of granola bars and water. On Saturday and Sunday, no shipments were sent. Six shipments were sent to Navy Seals training in Covert Location #1, only three of which consisted of granola bars and water.
