MIL-HDBK-419A 29 DECEMBER 1987 Volume 2 of 2 Applications Unfortunately, few Military Handbooks address the need for defense against electromagnetic pulse (EMP) and cybersecurity. While EMP has been thought of as a remote possibility (who in his right mind is going to launch a nuclear weapon of any kind against the U.S.?) Advances in non-nuclear EMP, miniaturization of electronics and autonomous drones suddenly brings EMP into the role of the possible. No longer would an adversary need to risk retaliation when a drone from an unknown source attacks a vital facility. The information in this book is part of the solution to the question "How do we defend against EMP?"
