Imagine this. Your brigade is part of a Corps level task force preparing to move into an allied country to push out an invading Army. The unit has been on site for several weeks and is just waiting for the order to attack. One day you get a call from one of your battalions informing you that their SIPR call manager has crashed and that they will need to reimage the system. You reach into your box of CD/DVDs to find the call manager disks and discover that you don’t have it…..FML
