PREFACE
Tactics is the art and science of employing all available means to win battles and engagements. Specifically, it
comprises the actions taken by a commander to arrange units and activities in relation to each other and the enemy. This
student text focuses on the organization of forces, minimum essential control measures, and general planning, prepara-
tion, and execution considerations for each type and form of offensive and defensive action.
This student text introduces concepts associated with the art of tactics associated with the conduct of offensive and
defensive actions. It cannot be read in isolation. To understand this text, the reader must understand the theory of
operational level art, the principles of war, and the linkages between the operational and tactical levels of war described
in FM 100-5, Operations. The reader should understand that during the conduct of operations a commandermay or
may not conduct offensive, defensive, stability, and support actions simultaneously. This conduct of simultaneous
actions is more likely to occur at higher tactical echelons. The reader should understand the plan, prepare, execute, and
assess cycle described in FM 100-34, Command and Control, and how that cycle relates to the military decision making
process (MDMP) described in FM 101-5, Staff Organization and Operations. What follows in this text flows from
these discussions and provides the foundation to understand the basics of tactical offensive and defensive actions and
build tactical skill.
The ability to seize and secure terrain, with its populations and productive capacity, is the distinguishing character-
istic of land forces conducting combat operations. This student text provides a common discussion of how commanders
from the battalion task force through the corps echelon conduct offensive and defensive tactical actions and their
supporting enabling operations. While it focuses on the tactics used to employ available means to win in combat; those
tactics require judgment in application.
This student text has sixteen chapters and four appendices divided into four parts. Part I describes the Art and
Science of Tactics, explains how the operational framework established in FM 100-5 applies at the tactical level, and
defines common tactical concepts and control measures. (NOTE : Chapter 2 contains one approach to an opera-
tional framework designed to meet the full range of requirements of todays Army that, in accordance with the
National Security Strategy, must remain engaged throughout the world while preparing for two major theaters
of war. I t is not the only approach to this subject and final decisions on this matter are pending within TRADOC
doctrinal development channels. Chapter 2 is not authoritative in nature and should be regarded as an article
presented for publication in a professional military journal.) Part II describes offensive operations. Within Part II,Chapter 4 discusses the basics of offensive operations. Each succeeding chapter discusses a specific type of offensive
operations and builds upon those basics of the offensive found in Chapter 4. Likewise, in Part III, Chapter 9 discusses
the basics of defensive operations with each succeeding chapter discussing a specific type of defensive operations.
Part IV discusses enabling operations, those operations conducted to assist the conduct of any of four types of
military actions (offense, defense, stability, and support). Since combined arms reconnaissance operations, combined

War is, above all things, an art, employing science in all its branches as its servant, but depending firest
and chiefly upon the skill of the artisan. It has its own rules, but not one of them is rigid and invariable.
As new implements are devised new methods result in its mechanical execution, but over and above all its
mechanical appliances it rests upon the complex factors of human nature, which cannot be reduced toformulas and rules.

THE ART OF TACTICS
Tactics is the art and science of employing
available means to win battles and engage-
ments. It is the employment of units in
combat. It is the ordered arrangement and
maneuver of units in relation to each other, the
terrain, and the enemy to achieve their full
lethality.
1-2. This is the capstone man-
ual for the tactical level of
offensive and defensive actions.
This is a manual for professionals and requires dedication and study to master. It is
authoritative and provides guidance in the form of combat-tested concepts and ideas
modified to take advantage of emerging Army and joint capabilities, focusing on the
tactics used to employ available means to win in combat. Those tactics are not prescri p-
tive in nature but require judgment in applic ation.
1-3. The principles of war are the fundamental
truths governing combat operations. Their
proper application is essential to the exercise of
command and the successful conduct of military
operations. The degree of application for each
principle varies with the situation. Blind adhe r-
ence to these principles does not guarantee
success, but each deviation may increase the risk
of failure. The principles of war lend rigor and
focus to the purely creative aspects of tactics and

provide a crucial link between pure theory and actual application. They are discussed in
FM 100-5, Operations.
1-4. The tactics and sup-
porting techniques and proce-
dures described in this manual
are only starting points for the
tactician who must understand
the difference between tactics
and techniques and proce-
dures. Tactics always require judgment and adaptation to the unique circumstances of a
specific situation. Both techniques and procedures are established patterns that can be
applied repeatedly with little or no judgment in a wide variety of circumstances. Ta c-
tics, techniques, and procedures (TTP) provide the tactician with a set of tools to use in
developing the solution to a tactical problem. The solution to any specific problem is a
unique combination of these TTP or the creation of new ones based on a critical evalu a-
tion of the situation. The tactician determines his solution by a thorough mastery of
doctrine and existing TTP, tempered and honed by experience gained through training
and operations. He uses his creativity to develop solutions for which the enemy is ne i-
ther prepared for, nor with which he can cope.
THE TACTICAL LEVEL OF WAR
1-5. The levels of war are doctrinal perspectives that clarify the links between strategic
objectives and tactical actions. Although there are no finite limits or boundaries b e-
tween them, the three levels are strategic, operational, and tactical. They apply to all
types of military actions.
1-6. The tactical level of war is the level of war at which battles and en-
gagements are planned and executed to accomplish military objectives
assigned to tactical units or task forces. Activities at this level focus on
the ordered arrangement and maneuver of combat elements in relation toeach other and to the enemy to achieve combat objectives. It is important to
understand tactics within the context of the levels of war. The strategic and operational
levels provide the context for tactical operations. Without this context, tactical oper a-
tions are reduced to a series of disconnected and unfocused actions. Engagements are
linked to battles. One or more battles are linked to winning major operations and ca m-
Tacticsare the arrangement of forces and capabil i-
ties on the battlefield.
Techniquesare the general and detailed methods
used by troops and commanders to perform as-
signed missions and functions, specifically, the
methods of using equipment and perso nnel.
Proceduresare standard and detailed courses of
action that describe how to perform tasks.

paigns, leading to operational success, which can lead to strategic success. (See FM
100-5 for a discussion of major o perations and campaigns.)
1-7. An engagement is a small, tactical conflict between opposing maneu-
ver forces, usually conducted at brigade level and below. An engagement
normally lasts only a short time minutes, hours, or a day. It can result from one
sides deliberate offensive movement against an opponent or from a chance encounter
between two opponents, such as a meeting engagement. An engagement can be a stand-
alone event or one of several related engagements comprising a battle.
1-8. A battle is a series of related tactical engagements that last longer
and involve larger forces than an engagement. It may affect the course of the
campaign. A battle occurs when a division, corps, or army commander fights for one or
more significant objectives. Battles are usually operationally significant, if not oper a-
tionally decisive.
1-9. Levels of command, size of units, types of equipment, or types of forces or compo-
nents are not associated with a particular level of war. National assets, such as
intelligence and communications satellites, previously considered principally in a strat e-
gic context, are an important adjunct to tactical operations. Actions can be defined as
strategic, operational, or tactical based on their effect or contribution to achieving str a-
tegic, operational, or tactical objectives, but many times the accuracy of these labels can
only be determined during historical studies.
1-10. Advances in technology, information age media reporting, and the compression
of time-space relationships contribute to the growing inter-relationships between the
levels of war. The levels of war help commanders visualize a logical flow of operations,
allocate resources, and assign tasks to the appropriate command. However, commanders
at every level must be aware that in a world of constant, immediate communications,
any single event may cut across the three levels. See FM 100-5, Operations, for a dis-
cussion of the other levels of war.
THE SCIENCE AND ART OF TACTICS
1-11. The tactician must understand and master the science and the art of tactics, two
distinctly different yet inseparable co ncepts.
THE SCIENCE
1-12. The science of tactics encompasses the understanding of those mili-
tary aspects of tactics capabilities, techniques, and procedures that
-

20/564
ST 100-40
1 - 4
can be measured and codified. The science of tactics includes the physical cap a-
bilities of friendly and enemy organizations and systems, such as determining how long
it takes a division to move a certain distance. It also includes techniques and procedures
used to accomplish specific tasks, such as the tactical terms and control graphics that
comprise the language of tactics. While not easy, the science of tactics is fairly
straightforward. Much of what is contained in this manual is the science of tactics
techniques and procedures for employing the various elements of the combined arms
team to achieve greater effects.
1-13. Mastery of the science of tactics is necessary for the tactician to understand the
physical and procedural constraints under which he must work. These constraints i n-
clude the effects of terrain, time, space, and weather on friendly and enemy forces.
However because combat is an intensely human activity the solution to tactical
problems cannot be reduced to a formula. This realization necessitates the study of the
art of tactics.
THE ART
1-14. The art of tactics consists of three interrelated aspects: the creative
and flexible array of means to accomplish assigned missions, decision
making under conditions of uncertainty when faced with an intelligent en-
emy, and understanding the human dimension the effects of combat on
soldiers. An art, as opposed to a science, requires the exercise of intuitive faculties
that cannot be solely learned by study. The tacticians study must be tempered and his
skill evolved through a wide variety of relevant, practical experiences. The more exp e-
rience the tactician gains from practice under a variety of circumstances, the greater his
mastery of the art of tactics.
1-15. The tactician invokes the art of tactics to solve tactical problems by choosing from
interrelated options including:
l Types and forms of operations, forms of maneuver, and tactical tasks.
l Task organization of available forces, to include the allocation of scarce r e-
sources.l Arrangement and choice of control measures.
l Tempo of the operation.
l Risks the commander is willing to take.
These options represent a starting point for the tactician to create a unique solution to a
specific tactical problem. Each decision represents a choice among a range of options,
each balances competing demands requiring judgment at every turn. While there may
-

21/564
ST 100-40
1 - 5
be checklists for techniques and procedures, there are no checklists for solving tactical
problems. The commander must not look for a checklist approach to tactics: instead, he
must use his experience and creativity to ou tthink his enemy.
1-16. The first aspect of the art of tactics is the creative and flexible application of the
tools available to the commander, such as doctrine, tactics, techniques, procedures,
training, organizations, material, and soldiers, in an attempt to render the enemys sit u-
ational tactics ineffective. The factors of mission, enemy, terrain and weather, troops,
time available, and civil considerations (METT-TC) are variables whose infinite mut a-
tions always combine to form a new tactical pattern. (Chapter 3 discusses the factors of
METT-TC.) They never produce exactly the same situation; thus there can be no
checklists that adequately address the unique situation. Because the enemy changes and
adapts to friendly moves during the planning, preparation, and execution of an oper a-
tion, there is no guarantee that a technique that worked in one situation will work again.
Each tactical problem is unique and must be solved on its own merits.
1-17. The second aspect of the art of tactics is decision making under conditions of u n-
certainty and demonstrated by the clash of opposing wills a violent struggle between
two hostile, thinking, and independent opponents with irreconcilable goals. Each co m-
mander wants to impose his will on his opponent, defeat his opponents plans, and
destroy his opponents forces. Combat consists of the interplay between these two op-
posing commanders, with each commander seeking to accomplish his mission while
preventing the other from doing the same. The tactician needs a high degree of creati v-
ity and clarity of thought to outwit a willing and able opponent.
the conflagration of battle had lit the sky just north of us. But each of us in
the headquarters unit had been so busy that we had not fully grasped the imme n-
sity of the struggle, or its destructiveness. But as the sky brightened, I looked
around and saw hundreds and hundreds of burned and twisted vehicles. Fifty I s-
raeli tanks lay shattered on the field. Around them were the hulks of 150
Egyptian tanks plus hundreds of APCs, jeeps, and trucks Here and there Israeli
and Egyptian tanks had destroyed each other at a distance of a few meters, barrel
to barrel. It was if a hand-to-hand battle of armor had taken place. And insidethose tanks and next to them lay their dead crews you could see Egyptian and
Jewish dead lying side by side, soldiers who had jumped from their burning tanks
had died together. No picture could capture the horror of the scene; none could
encompass what had happened there. On our side that night we had lost 300 dead
and hundreds more wounded. The Egyptian losses were much, much heavier.

1-18. The third and final aspect of the art of tactics is understanding the human dime n-
sion what differentiates actual combat from the problems encountered during training
and in a classroom. Combat is one of the most complex human activities characterized
by friction, uncertainty, and chance. Success depends at least as much on this human
aspect as it does on any numerical and technological superiority.
1-19. These human aspects cannot be ignored. The tactician seeks to recognize and e x-
ploit indicators of fear and weakness in his enemy, and to defeat the enemys will, since
soldiers remain key to the generation of combat power. More than any other human a c-
tivity, continuous combat operations against an intelligent enemy takes a toll on soldiers,
severely straining their physical and mental stamina. This creates in soldiers the tang i-
ble and intangible effects of courage, fear, combat experience, exhaustion, isolation,
confidence, thirst, and anger. If left unchecked, these effects can result in decreased
vigilance, slowed perception, inability to concentrate, communication difficulties, and
an inability to accomplish manual tasks.
1-20. Leaders must be alert to indicators of fatigue, fear, lapses in discipline standards,
and reduced morale in friendly and enemy soldiers. They must work to counteract the
effects on the friendly force while taking measures to enhance these effects on the e n-
emy. When the friendly force has the initiative, it can force the enemy to conduct
continuous operations to react to friendly actions and then exploit the effects of contin u-
ous operations on the enemy. These conditions can have a cumulative effect on units
that can lead to collapse. The commander must understand how these effects impact
human endurance and factor them into his plans. He must understand the limits of h u-
man endurance in combat. This is the subtle difference between pushing soldiers
beyond their limits to exploit success versus resting them to prevent the collapse of unit
cohesion. (Additional discussion concerning the effects of continuous combat operations
is found in FM 100-34, Command.)
HISTORICAL EXAMPLE

pens and illustrates the need for the tactician to combine the effects of the science of
tactics with his application of the tactical art.

COWPENS, 17 JANUARY 1781
On 17 January 1781, American BG Daniel Morgan defeated British LTC Tarleton a t the Cowpens in
South Carolina in a battle that captures the essence of the art of tactics the use of intuitive faculties that
cannot be learned solely by study. Although outnumbered, Morgans troops fought and won against a prev i-
ously unbeaten opponent. The battle achieved decisive results with strategic signif icance.
In December 1780, BG Morgan was sent with 600 men into the South Carolina highlands under orders to
protect Americans, forage, and threaten British control of the highlands. His opponents force, LTC Tarl e-
tons British Legion numbered nearly 1,000 men and consisted of a combined cavalry -infantry force reinforced
with additional infantry and two three-pounder guns, was sent in pursuit of Morgan. By 16 January 1781,
Tarleton had closed to within six miles of Morgan's force.
Having known of Tarleton's mission since 14 January, Morgan obtained information on Tarleton's tactical
style while he began to retreat. With Tarleton so close on 16 January and his own camp nearly six miles from
the Broad River, Morgan decided to fight at the Cowpens. While the two forces were now roughly the samesize, Morgan had only about one-third of the cavalry, one-third of the regular line infantry, and no artillery.
However, his militia force's rifles had a
longer range than the British muskets,
and the terrain allowed him to mask his
reserves from view. Morgan deployed
his forces on the battlefield, confident
that Tarleton would not attempt to
flank his position . Rather, Morgan
believed that Tarleton would initially
attack him with part of his cavalry
supported by infantry, wait for confu-sion, and then exploit those
vulnerabilities with his cavalry reserve.This had been his pattern of operations
in previous engagements with the
Americans.
In the main line of battle, Morgan
placed his Continentals and Virginia
militia, who were former Continentals,
on the military crest of the rise under
COL Howards command. They num-
bered 450. About 150 meters downhill,
toward the expected reaction of the
enemy, he stationed the bulk of his
militia under the command of COL
Pickens. Another 150 meters down thehill, he positioned a skirmisher line of
150 militia riflemen. Behind the hill,
he placed LTC Washingtons 120-
strong cavalry force in reserve. Each
line was within rifle range but out of
musket range of the line behind it. As
explained to his men the night before,
skirmishers only needed to fire one or
-

two shots and then retire to the second line. In turn, the militia in the second line only needed to fire two
volleys. Then they could retire to their left around to the rear of the hill and, protected by the cavalry, reform.
The cavalry would counterattack British cavalry as the situation allowed, guard the militia horses, or cover a
retreat if necessary.Tarleton deployed his forces from their march formation into a line, with three light infantry companies
on the right, the Legion infantry in the center, and one regular British battalion on the left of this main line.
He stationed one troop of cavalry on each flank of the main line, and one, three-pounder gun on either side of
the Legion infantry. He kept the other regular British battalion and the remainder of his Legion cavalry in
reserve. The British immediately came under fire from the skirmishers. Tarleton sent a troop of dragoons to
disperse them while his main forces deployed. The dragoons lost 15 of 50 men. The skirmishers retired to the
American second line.
Tarleton then assaulted the second line. His artillery opened fire, but a pparently on the third line. The
American rifle fire disrupted his formation. When his forces closed to within 50 meters of the second line,
they received a volley from the militia that staggered and further disrupted his forces. The expected second
volley from the militia was more ragged as the militia began to withdraw. Seeing this movement, Tarleton
ordered his right-hand troop of dragoons to charge the militia as it withdrew. The American cavalry charged
this troop and overwhelmed it, driving the dragoons off the field in accordance with Morgans plan.As the British moved hastily forward to assault the main American position, they further lost their coh e-
sion as a firefight between the two forces ensued. Tarleton ordered his reserve infantry battalion up to the left
of his line for this assault, and the cavalry troop on his left to encircle the American line. This move ou t-
flanked the American line. Mor
