Advisers to the Nation on Science, Engineering, and Medirine
.
The National Academy of Sciences is a private, nonprofit, self-perpetuating society of
distinguished scholars engaged in scientific and engineering research, dedicated to the
furtherance of science and technology and to their use for the general welfare. Upon the
authority of the charter granted to it by the Congress in 1863, the Academy has a mandate
that requires it to advise the federal government on scientific and technical matters.
Dr. Bruce M. Alberts is president of the National Academy of Sciences.
The National Academy of Engineering was established in 1964, under the charter of the
National Academy of Sciences, as a parallel organization of outstanding engineers. It is
autonomous in its administration and in the selection of its members, sharing with the
National Academy of Sciences the responsibility for advising the federal government.
The National Academy of Engineering also sponsors engineering programs aimed at
meeting national needs, encourages education and research, and recognizes the superior
achievements of engineers. Dr. Wm. A. Wulf is president of the National Academy of
Engineering.
The Institute of Medicine was established in 1970 by the National Academy of Sciences
to secure the services of eminent members of appropriate professions in the examination
of policy matters pertaining to the health of the public. The Institute acts under the
responsibility given to the National Academy of Sciences by its congressional charter to
be an adviser to the federal government and, upon its own initiative, to identify issues of
medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute
of Medicine.
The National Research Council was organized by the National Academy of Sciences in
1916 to associate the broad community of science and technology with the Academy's
purposes of furthering knowledge and advising the federal government. Functioning in
accordance with general policies determined by the Academy, the Council has become the
principal operating agency of both the National Academy of Sciences and the National
Academy of Engineering in providing services to the government, the public, and the
scientific and engineering communities. The Council is administered jointly by both
Academies and the Institute of Medicine. Dr. Bruce M. Alberts and Dr. Wm. A. Wulf are
chair and vice chair, respectively, of the National Research Council

Preface
As part of the nation's national security strategy, naval forces remain de-
ployed throughout the world, engaged in or ready to support operations ranging
from training exercises with joint and allied coalition partners, to humanitarian
relief efforts, to peacekeeping and peace enforcement, to combat. Non-lethal
weapons provide one means by which expeditionary forces can accomplish their
missions, particularly in urban areas, with a reduced likelihood of death and
injury to non-combatant civilians who might be encountered, for example, in
hostage rescue or human shielding operations. As a result of the National De-
fense Authorization Act of 1996 and because of Marine Corps initiative and
experience, the Commandant of the Marine Corps was designated the executive
agent for joint Service research, development, testing, and evaluation of non-
lethal weapons and non-lethal weapons technologies.
Operating with a yearly budget of approximately $25 million, the Joint Non-
Lethal Weapons Directorate (JNLWD) is executing these responsibilities. Less
than $1 million of this amount is used to support new technology development.
Currently, the role of the JNLWD in areas related to information warfare and
psychological warfare and with respect to single-Service activities is limited to
coordination and integration. At issue for the Department of the Navy is to what
extent and in what areas Navy-sponsored science and technology should provide
a research base for developing non-lethal weapons capabilities.
Non-lethal weapons consist of a diverse array of individual weapons that mini-
mize fatalities and undesired damage to property and the environment. They func-
tion in three realms: those of (1) counterpersonnel objectives, which include con-
trolling crowds; incapacitating individuals; denying areas to personnel; and clearing
personnel from facilities, structures, or areas of operation; (2) countermateriel objec-

fives, which include denying areas to vehicles, vessels, or aircraft, and disabling or
neutralizing vehicles, vessels, aircraft, or equipment; and (3) countercapability ob-
jectives, which include disabling or neutralizing facilities and systems and denying
use of weapons of mass destruction.
Non-lethal weapons technologies cover a broad spectrum, including areas
related to the development of acoustics systems, chemicals (e.g., antitraction
materials, dyes, markers, and malodorants), communications systems, electro-
magnetic and electrical systems, entanglement and other mechanical systems,
information technologies, optical devices, non-penetrating projectiles and muni-
tions, and many others. Combinations of non-lethal and lethal weapons are
possible. Synergy of non-lethal weapons with psychological, information, and/or
electronic warfare in a networked fashion could be especially effective. As non-
lethal weapons are developed and acquired, it is especially important that train-
ing, delivery, deployment, control, logistics, maintenance, and doctrine for use
are in hand. Forward-deployed, distributed naval forces offer great potential for
timely use of non-lethal weapons in a variety of scenarios.

review comments, editing the report, and conducting the required security review
necessary to produce an unclassified report.
Following completion of the security review a prepublication copy of the
report was released to the public on November 4, 2002. Subsequent to that
release, it became apparent that the Department of Defense and the Department
of State have differing legal interpretations of the Chemical Weapons Conven-
tion as it pertains to the development of chemical non-lethal weapons for military
purposes. As a consequence, and in recognition that it was not the mandate of the
committee to conduct a legal review of the permissibility of non-lethal weapons
as it relates to the Chemical Weapons Convention (and other national and inter-
national law and treaties), a brief discussion of legal considerations has been
excised from the final report. In doing so the committee recognizes that it is of
paramount importance that the Department of Defense and the Department of
State clarify the legal interpretations of the Chemical Weapons Convention so
that both the operational and technical communities can move forward under
consistent guidelines.

Prologue
.,
September 11, 2001, was a defining day in the history of the United States of
America, if not the world. The unprecedented disasters in New York and Wash-
ington, D.C., have placed the nation on a wartime footing, and we have formally
acknowledged our battle against terrorism. The implications for warfighting and
law enforcement have yet to be fully understood, but most would agree that
profound shifts in emphasis and investment are likely to come. In rooting out
terrorism's infrastructure, there will be times when controlled application of
force will be essential and unconstrained violence counterproductive to our stra-
tegic goals. Moreover, punishing attacks that destroy the overt support system
for terrorists will not be sufficient to weed out well-hidden infrastructure, some of
which already resides on U.S. soil. As the immediate emotional circumstances
fade, the need to isolate a few individuals, both in the United States and abroad,
most likely in and amongst civilian populations, will remain critically important.
In that context, non-lethal weapons may play an even greater role in matters of
national security.
Of particular concern to the Navy will be yet greater emphasis on base
security and force protection as the links between the events of September 11
and the USS Cole incident begin to be made. This report addresses those
issues but could not fully appreciate the new complexities in which those
missions are likely to be executed. For the U.S. Marine Corps the focus on
Military Operations in Urban Terrain is likely to take on added importance,
with minimization of collateral casualties and damage being of the utmost
importance for maintaining fragile coalition relations with Middle Eastern
states in particular. This report emphasizes the role of non-lethal weapons

for those missions, but the emerging political climate elevates to a strategic
level the importance of controlled use of force.
In this milieu, the development and deployment of more capable non-lethal
weapons should be given a higher priority. This report was in review on Septem-
ber 11. None of its recommendations have been altered by the events of that
day but the urgency in their acceptance and implementation has.
