  A computer can be made as powerful as required. In fact the power lies in what the computer can be used to control. There is no limit and military generally uses the best computer/fastest computers anyway. Military can use it to defend the nation in war (eg automatic anti-missile guns, radars, intruder tracing systems/ advance navigation systems/ spying on other nations at war etc)

  The military probably have some of the best computers in the world! The most powerful computer in the world (I think, Dhvanil might know more than me on this) is called the K computer in Japan and can do 10,000,000,000,000,000 calculations per second, more than the human brain!
