US Military Advantage in Cyberspace is Challenged

The superiority of the US military in cyberspace, which once could be taken for granted, is gradually eroding, says an Army Field Manual published this week.

In the past decade, “U.S. forces dominated cyberspace and the electromagnetic spectrum (EMS) in Afghanistan and Iraq against enemies and adversaries lacking the technical capabilities to challenge our superiority in cyberspace.”

“However, regional peers have since demonstrated impressive capabilities in a hybrid operational environment that threaten the Army’s dominance in cyberspace and the EMS,” according to the new Field Manual.

“Rapid developments in cyberspace and the EMS will challenge any assumptions of the Army’s advantage in this domain. While it cannot defend against every kind of intrusion, the Army must take steps to identify, prioritize, and defend its most important networks and data.”

The underlying principles of US Army operations in cyberspace were described in the new Field Manual 3-12, Cyberspace and Electronic Warfare Operations, 11 April 2017 (unclassified, 108 pages).
