"Projected into battle-zone by three dimensional transport devices, this futuristic soldier will be able to arrive and surprise his enemy with a force and suddenness never before known."

During the Korean and Vietnam wars, helicopter warfare became common.

The doctrine of "air assault" with helicopters continues to this day, and soldiers are often transferred to and from the battlefield in a variety of different helicopter types. The use of helicopters has also greatly reduced the number of combat deaths since wounded soldiers are able to get medical attention much quicker.
