How is the Internet connected to the military ? 

The origin of the Internet as we known it today goes back to a military invention called ARP Ante.

   ARPA stands for the Advanced Research Projects Agency, a branch of the military that developed top secret system and weapons, during the Cold War.
    ARP Anet was designed at the request of the US government, to connect computers at the Pentagon and Cheyenne Mountain, the US nuclear weapon control center.

  ARP Anet expanded quickly to include the computers at research institutions and universities. It created a network of geographically separated computers that could exchange information via a newly developed protocol-or rule for how computers interact called NCP. In many ways, ARP Anet can be called the grandfather of the Internet.
