I may have mentioned this in a previous article about the Newton, but it was used to coordinate battlefield information during a Marine Corps war fighting experiment called Hunter-Warrior, which was part of a program called Operation Sea Dragon.Taken from This desription:
The Hunter Warrior Experiment showed how lightly-armed units can dominate large coastal regions, not by landing on the beaches, but by leaping over them in V-22s, spreading out and operating deep inside enemy territory. They used hand-held Apple Newton computers to send out hard-to-detect digital bursts to call in long-range, precision firepower from ships, choppers, fighters and other military assets.
This experiment tested the tactical concept of squads acting as independent elements on the dispersed battlefield. To do this, a communications system allowed the squads to talk to their headquarters elements at distances of 100 miles. This type of radio did not exist, so we took existing palm-top computers, tied them into a digital radio and built a communication infrastructure of towers in the desert. The result was a communication system that was a "surrogate" and allowed us to see if squads could act as independent units on the dispersed battlefield.
