Nanotechnological Era

The Nanotechnological Era is possibly the greatest era of all human history. The construction and research of nanorobotics allowed man to push beyond the limits. This played a huge role in the upcoming World War IV.

Nanorobotics
With the introduction of nanorobots, casualties in the battlefield have significantly decreased. Once a person dies, thier biometric data is stored on a computer, which then transfers nanorobts to the dead person. They begin to heal the person, by replacing dead tissue, blood vessels and all other nessecary functions. There is exceptions however, if there is no nanodeplacement field (the device that emits nanorobots) within a 3.5km radius, the person will be permamently dead. This explains the scenes seen in Call of Duty: Ghosts II, were a main character dies.

Nano-Digital Processing
Nano-Digital Processing has allowed a small tablet be able to control a full-sized combat-operational UAV, or Heads Up Display (HUD) glasses. The key lies in the nanonscopic components used to make electronics and digital appliances which are so small, they can't even be seen with a microscope.
