Air-borne troops will depend more than ordinary infantry on the use of radio, at least until they have overcome any immediate opposition and have become a coordinated force. Thereafter, they will act as ordinary infantry and will not be so entirely dependent on radio communication, except for traffic with their rear headquarters. In the early stages of an operation, much depends on reports being received at rear headquarters from reconnaissance aircraft and forward units; in the later stages, the key points are the "flying radio stations" and the radio sets at headquarters of forward groups. It should be possible to jam some of this traffic with good results.
