It may also provide the first long-range system to recover from a nuclear attack. It will be the first, and frequently the only, means of communicating with fast-moving or widely separated units. High frequency radio is quickly deployable, securable, and capable of data transmission. Coupling this with the problems that can be expected in deploying multichannel LOS systems with relays to keep up with present and future operation, high frequency (HF) radio and the near-vertical incidence sky-wave (NVIS) mode take on new importance. The standard communications techniques used in the past will not support the widely deployed and the fast-moving formations we intend to use to counter the modern threat.
