I do believe that the title is somewhat misleading. By Electronic, the name is referring to elecromagnetic warfare; using radio and wireless telecom to communicate, to block enemy communication, to disrupt any hardware or software that is stupid enough to run on radio signals, and to deceit any enemies using radio or other forms of telecom. This manual describes what it is, how it works, and what a commander of an operation can do in terms of electronic warfare.
Despite that, i still believe there is some interesting stuff in there including a lot of terminology of what this stuff is. Also has a listing of military, private, and public radio bandwidths.
