I think this is a very interesting story because I did not realize that the army did not already supply something similar to this for it's soldiers already.
The smartphone idea is brilliant because this will allow the military to be even more productive and anything that will give the military an advantage like this is a good thing. It's a good idea too, that they are ensuring the productivity level will be high by only allowing pre-approved to apps to be downloaded onto the phone. I also think picking android is the way to go too because of the popularity of the phone it's user friendliness.
