Wired is reporting that the US Army has chosen to use an Android-based phone as its first smartphone for US troops. Now in prototype stage, the US Army Android smartphone is called the Joint Battle Command-Platform and will have its SDK released to Android developers in July. Currently, the phone has mapping apps and apps that track where friendly forces are.
It's really no surprise the US Army opted for an Android phone over an iPhone. Android phones allow the US Army to build their own specific hardware and not rely on a company like Apple for system-level improvements.
