Technique of modern tactics

In Short

Major P. S. Bond and Major M. J. McDonough present a rigorous, practical manual on troop-leading methods for mixed-arms detachments in early twentieth-century warfare. Designed as an instructional text for the U.S. Army, National Guard, and officer service schools, the book translates abstract tactical doctrine into concrete operational decisions. It walks officers through the meticulous calculations required to march, protect, supply, engage, and withdraw combined forces—comprising infantry, cavalry, field artillery, engineers, signal, and sanitary troops. Through standardized field order formulas, map maneuvers, and detailed tactical scenarios, the text demonstrates how commander clarity and disciplined logistics govern the chaos of the battlefield. It endures as a precise historical snapshot of American doctrine at the dawn of mechanized warfare.

The Story

The intellectual arc of the text moves from fundamental operational principles to complex tactical maneuvers, systematically training an officer to command a detachment of all arms. The exposition begins with the administrative and mathematical foundations of troop leading. A commander must first master time, distance, and road space. Calculating column lengths, elongation on the march, and minimum camping footprints forms the baseline of command; without these metrics, a force cannot arrive at the battlefield intact or adequately supplied.

From basic logistics, the text progresses to the service of security and march protection. The authors outline the mechanics of advance guards, flank guards, and rear guards. An advance guard clears the line of march and absorbs initial hostile contact, while flank guards require careful calculation to avoid dispersing combat power unnecessarily. The narrative of tactical deployment expands as the authors address outposts and bivouacs, detailing how to establish lines of resistance, pickets, and sentry squads to protect a resting army from surprise attacks.

The core of the book addresses direct combat operations, divided into offensive, defensive, and encounter actions. In a meeting engagement, speed of decision and seizing the initiative are paramount. The text guides the reader through the mechanics of launching a prompt attack before the enemy can establish a defensive position. When facing a prepared defender, the authors detail the coordination between a holding attack and an enveloping attack. Here, field artillery plays a decisive role: initial counter-battery work gives way to sweeping hostile infantry lines with shrapnel, creating a moral and physical effect that allows friendly infantry to advance. The text explicitly outlines artillery ranges, flash defilade, and the necessity of advancing by echelons to maintain uninterrupted fire support.

As combat scenarios become more complex, the authors examine specialized operations. River line operations require careful orchestration: the attacker must deceive the defender using feints while engineers collect bridging equipment and construct crossings under infantry cover. In defense, river lines rely on mobile reserves and aerial reconnaissance to detect enemy passage points early. Night attacks demand extreme simplicity, close touch, and bayonet usage, deliberate control replacing complex maneuvers.

The tactical arc concludes with the difficult maneuvers of retrograde movements and logistical sustenance. Withdrawing a force committed to action is presented as one of the most perilous military operations, often requiring a dedicated rearguard or supporting position to cover retiring troops under darkness. Parallel to these combat movements runs the logistical lifespan of a division: supply trains, ammunition columns, and field bakeries cycle constantly between railheads and the firing line. Motor transportation emerges as a vital innovation, expanding the operational reach of the force, accelerating wounded evacuation, and altering the velocity of modern military logistics.

How It Unfolds

The calculations of command The manual opens by establishing the mathematical realities of troop leading, detailing road space, column elongation, and camp layout metrics. Officers learn that tactical success rests initially on calculating the exact physical footprint of troops, horses, and wagons on the march.

Issuing the field order The text introduces the standardized, four-or-five-paragraph field order developed by the Army Service Schools at Fort Leavenworth. The authors stress replacing rambling, verbose commands with crisp, epigrammatic phrasing such as "March conditions now cease" to eliminate ambiguity.

Screening and flank security The guide details the deployment of advance, rear, and flank guards to protect the main body. Commanders are instructed to evaluate seven specific terrain and distance questions before committing troops to a flank guard, favoring active mounted reconnaissance over force dispersion.

Coordinating the arms in attack The narrative moves into offensive battle tactics, illustrating how infantry, cavalry, artillery, and engineers combine. Field artillery engages enemy positions with shrapnel to suppress infantry fire, while engineers clear obstacles and maintain communications for the advancing force.

Special operations and river lines Tactical instruction addresses complex environments, detailing the feints, engineer reconnaissance, and bridgehead establishments necessary to force a river crossing. Night operations are outlined with an emphasis on simple plans, watchwords, and relying on the bayonet to avoid confusion.

Retrograde movements and supply The final sections cover the mechanics of withdrawing under fire, utilizing successive supporting positions to preserve the force. The text concludes with an analysis of supply lines, ammunition replenishment, and the emerging role of motor trucks in extending the army's operational reach.

The People

The Supreme Commander The central decision-maker who must weigh intelligence, evaluate terrain, and issue unambiguous field orders. He wants to maintain control over his entire force, achieve tactical objectives, and avoid the premature dispersion of his troops. In every situation, from a meeting engagement to a withdrawal, he bears the burden of calculating time and space to preserve his command's fighting integrity.

The Field Artillery Commander The key coordinator of supporting fire whose primary mission is supporting the infantry through critical battle stages. He strives to secure favorable positions—ideally with flash defilade and clear ranges between 2,500 and 3,500 yards—while avoiding unnecessary movement once committed. His success is measured by his ability to maintain continuous fire on enemy positions without endangering friendly troops.

The Engineer Officer The technical problem-solver responsible for mobility, counter-mobility, and field fortifications. He seeks to clear obstacles, construct bridges, build recessed traversed trenches, and prepare demolitions under fire. Whether facilitating an advance across a river or delaying a pursuing enemy by destroying stream crossings, he serves as the force's primary tactical enabler.

The Outpost Commander The officer charged with securing the army's rest and preventing surprise attacks while in camp. He wants to establish an unbreakable line of observation and resistance using pickets, supports, and sentry squads. He must position his reserve centrally, manage examining posts, and ensure his detachments can hold their ground until the main body can deploy.

In Its Own Voice

"The ability to do this must be acquired by practice in writing orders to cover concrete cases."

The authors emphasize that theoretical knowledge of military regulations is insufficient without continuous, practical application in drafting clear operational directives.

"Whatever the situation the mission of the field artillery is to support the infantry, particularly at the critical stages."

This passage encapsulates the core combined-arms doctrine of the manual, defining the auxiliary role of supporting arms relative to the primary offensive element.

"The motor car, in short, aids in strategic and tactical concentration of troops and heavy guns and in the defense of isolated points, lessens fatigue, and extends the theater of command, inspection and reconnaissance."

Writing during a period of technological transition, the authors summarize how mechanical transport fundamentally expands the speed and spatial boundary of military operations.

What It's Really About

Beneath its procedural instructions, Technique of Modern Tactics is an argument for systematic order against the chaotic nature of combat. The book asserts that military command is not an intuitive art reserved for geniuses, but a repeatable, professional discipline grounded in clear communication, standardized doctrine, and precise spatial planning.

The text wrestles with the problem of control in increasingly lethal, distributed battlefields. As long-range artillery, machine guns, and aerial reconnaissance expand the zone of danger, individual units must disperse to survive. The book asks how a commander can maintain unity of effort when troops are spread across wide fronts. Its answer lies in structural routines: rigorous field orders, standardized staff procedures, and an uncompromising understanding of how different arms—infantry, cavalry, artillery, and logistics—depend on one another to achieve a single mission.

Why Read It Today

Historians, military enthusiasts, and readers interested in early twentieth-century doctrine will find this text an authentic primary document. Written on the eve of America's entry into World War I, it captures the U.S. Army at a transitional moment: traditional cavalry tactics and horse-drawn supply trains sit alongside machine guns, field entrenchments, armored cars, and aeroplane reconnaissance.

Reading the manual feels like sitting in a classroom at Fort Leavenworth in 1916. The prose is clean, direct, and authoritative, free from decorative language or melodrama. The satisfaction of the book comes from its granular detail—calculating how many yards a wagon train occupies on a dirt road, or how wide a trench traverse must be to absorb high-explosive shell bursts.

The primary difficulty for a modern reader lies in its technical density. The text is dense with military acronyms, precise spatial dimensions, and structured order formats designed for professional study rather than casual reading. Yet for those fascinated by operational logic, the manual offers an unfiltered look at how officers were trained to think, plan, and communicate before the advent of modern digital warfare.
