Securing the military network
Right now the military is looking at the National Security Agency (NSA) to produce a series of standards for encryption on the battlefield. Of course, this process can take over a year, which would mean devices and software that are optimized for the standard likely won't be released for another year after that.
A delay that lasts a year or longer is a huge deal for technology today. Look at what we have this year when compared to last. Quad-core phones when we hardly had dual-core last year, processors that allow for twice the processing power! Standards need to reflect the technology at the time, but when an organization is so slow to adapt to new technology it becomes difficult to design them. What is 256 bit encryption isn't useful anymore when the new standard comes out because quantum computers became more common?
It's strange that an organization that relies on the latest technology is incapable of actually getting that technology into the hands of soldiers. With all the resources at its disposal the DoD needs to evolve and cut through whatever red tape is slowing the process of creating a good communication standard and start giving warfighters the functionality civilians already have. It's kind of crazy that I can download an app that locates my friends, but a warfighter doesn't have the ability to do the same thing for his squad.
