5. Nanobots
Getting medical aid to soldiers is tricky and sometimes impossible. However, with the development of nanotechnology, it might soon be possible for a soldier to carry medical aid in their bloodstream. Nanobots being developed for medical applications could be injected into a soldier's bloodstream. They work on a molecular level to fight disease and even carry out repairs, and could protect against everything from infection to the effects of chemical weapons. It may also someday be possible to use these bots to speed up the healing process or even control things like shock and bleeding in the case of injury. The technology is a little while off, but this would go a long way to making soldiers less vulnerable in dangerous situations.
