While the Cyber Defense of the United States is the responsibility of Cyber Command, the US Army is currently deploying cyber forces intended to intervene in support of contact forces, over the entire electromagnetic spectrum. The 915th Cyber Warfare battalion is already in charge of training and equipping 12 cyber teams of 45 soldiers, who will intervene at the scale of the division, in support of the forces on the electromagnetic spectrum, both from a defensive point of view, to preserve the integrity of control and communication systems, that offensive.
In parallel, the US Army joins the Joint Cyber Warfighter Architectur programe, intended to provide the tools and mythologies of cyber warfare, under the control of Cyber Command.
Several recent incidents have shown the vulnerability of NATO forces to a Cyber offensive, as well as to actions combining electronic warfare and cyber, notably during the Russian exercise Zapad 2017, or more recently during the NATO exercise Trudent Juncture 2018. If Russia has developed proven know-how in this area, China is not left out, the activity of Chinese hackers both in terms of denial of access and theft of information attests to this.
Far from being a high-level subject, cyber and electronic warfare capabilities have become essential to a force claiming to intervene in a “high intensity” environment.
