Military Analyst Breaks Down Modern Warfare: The Three-Layer Logic of Tactics, Operations, and Strategy

In a conversation on the Lex Fridman podcast, a military analyst systematically broke down several key levels for understanding modern warfare. The discussion did not stop at recounting specific battlefield developments; instead, it offered an analytical framework—from squad- and platoon-level engagements on the battlefield, to multi-branch coordination at the operational level, to strategic choices at the national level. For anyone trying to make sense of modern conflict, this layered logic is more valuable than simply tracking arrows on a map.

Tactical Level: Maps Matter, but You Can't Look Only at Maps

The analyst defined the tactical level as "the fine details on the battlefield"—how infantry advances, how drones are used, the force ratios between the two sides in specific engagements, and how these change day by day. These details may seem trivial, but they are the basic material for judging the direction of a war.

He emphasized that information at the tactical level directly affects strategic judgment. The reason is that progress on the battlefield shapes the expectations of military and political leaders about "who has more bargaining chips and who has the upper hand," and these expectations seep into the negotiating table between the two sides. In other words, gains and losses on the map do not by themselves determine the outcome of a war, but they determine who speaks more forcefully at the negotiating table.

However, the analyst also cautioned against becoming overly obsessed with maps. What is truly worth observing is "who is adapting and who is not." Citing the situation in 2026 as an example, he pointed out that the side gradually falling behind in adaptability and suffering greater casualties and battlefield reversals is Russia. The value of this judgment lies not in the fall of any specific location, but in what it reveals about the difference between the two armies in the speed of learning and adjustment.

The "adaptability" mentioned in the text is often called adaptation in military theory, distinct from mere flexibility. Adaptation emphasizes whether a military, after encountering unexpected friction, can quickly identify problems, adjust organization, tactics, logistics, and command processes, and feed the lessons back into the next round of operations. Assessing adaptation usually involves several indicators: the cycle from the emergence of a new tactic to its widespread adoption, the speed of equipment and organizational adjustments, trends in casualty rates, and whether the command level allows subordinates to experiment and make mistakes. This is also why the analyst regards "who is adapting and who is not" as more important than gains and losses at a single point on the map—it reflects the gap between the two sides in organizational learning speed.

Operational Level: A Concept Contested Even Within the Military

When discussing the "operational level," the analyst deliberately began with a disclaimer: this concept is itself contested within military circles. He knows many military people who believe there is no independent "operational level" and recognize only the existence of "operational art." He even joked that whenever he raises this topic, a group of Army majors is ready to jump up and debate.

Setting aside the terminological dispute, the substantive content of the operational level is clear: it concerns the organization of intelligence, logistics, and fire support, as well as the coordinated action of different units for a clear objective. Unlike the squad-platoon-company scale of the tactical level, the operational level deals with large formations at the corps and army level.

The analyst sketched the shape of operational planning with a series of questions: how to create conditions, how assault forces enter, who the second echelon is, who exploits success after victory, what alternatives exist after failure, and finally how to consolidate gains. This is a complex engineering effort with phases, sequences, and contingency plans, usually completed by a staff team.

Ideally, the operational level serves as a bridge—translating military strategy into executable action, so that every successful military operation points to a clear political objective rather than fighting for the sake of fighting.

"Operational level" corresponds in U.S. military terminology to the operational level of war, usually translated in Chinese as "战争战役层级," referring to the intermediate level between tactics and strategy. It deals with achieving operational objectives within a theater or campaign direction through a series of battles and maneuvers. This concept was formally established in the U.S. Army's 1980s Field Manual 100-5, with the aim of filling the analytical gap between "battle" and "war." Critics argue that it artificially fragments the continuum between tactics and strategy, and that the term "operational art" itself implies a skill rather than an independent level—which is the origin of the controversy within military circles.

Strategic Level: The Best Strategy Lies in What You Choose Not to Do

In the analyst's view, the core of military strategy is a "theory of success"—why your logic of action holds and why you do this rather than that. He believes that the place where strategy most reveals the truth is often not what it chooses to do, but what it chooses not to do. For analysts, this is the most informative part.

Strategy has two other easily overlooked characteristics. First, strategy cannot be changed frequently, or it ceases to be strategy; but any good strategy rests on core assumptions, and once those assumptions are falsified, adjustments must be made. The analyst said bluntly that many wars are fought badly precisely because decision-makers know the assumptions no longer hold but still plow ahead with the original strategy. Second, strategy is iterative—it interacts with the opponent's strategy, requiring continuous assessment of how one's own strategy performs against the opponent's intentions, and correction accordingly.

"Theory of success" is a common concept in strategic planning, referring to a chain of causal assumptions about "why this logic of action can achieve the expected political objectives." It usually includes: definition of the core problem, expected objectives, the course of action adopted, and key assumptions (such as opponent reaction, ally cooperation, and resource sustainability). The reason strategy must state a theory of success is to make assumptions testable—so that once a key assumption is falsified by reality, it can be identified and corrected in time, rather than discovering only after failure that the original plan was built on false premises. This is also the theoretical basis for the text's emphasis that "strategy cannot be changed frequently, but must be adjusted when assumptions are falsified."

The Gap Between Tactics and Strategy

One insightful point in the conversation concerns the risk of disconnect between tactics and strategy. The analyst noted that tactical change is fast and must keep pace with technological evolution, but there is an inherent tension between strategy and tactics.

He gave failure cases in two directions. In one, a staff team writes a beautiful strategy document, but the forces simply lack the ability to execute it. In the other, the military knows only how to fight but not how to design campaigns—it may fight well tactically, but has not thought through how these battles accumulate into military victory, so there is no real "campaign" to speak of.

This also explains why layered analysis is so important: focusing only on tactics leads to the noise of daily battle reports; talking only about strategy detaches from battlefield reality. Truly valuable judgment comes from mutual verification across the three levels—whether tactical changes are rewriting strategic expectations, whether operational planning is delivering on political objectives, and whether strategic assumptions still hold.

This framework is not tailored to any single war, but it offers a reusable thinking tool. For readers following modern conflict, the next time you see news of a shift in the front line, it is worth asking one more question: what level of change does this belong to, and what is it affecting upward?

The phenomenon in the text of "only battles and no campaign design" is often described in military terminology as a lack of operational art or operational planning. Operational art concerns how to arrange a series of tactical actions into a sequence pointing toward the same objective: sequencing, force allocation, use of reserves, exploitation and consolidation of gains. Without this layer, forces may win many engagements but fail to accumulate them into an operational victory, because each victory is not converted into key damage to the enemy system. Conversely, having only a beautiful operational plan without tactical execution capability produces the other failure mentioned in the text—the plan cannot be implemented. Together, the two show that the middle layer cannot be omitted.

One-line Summary

A military analyst uses a three-layer framework of tactics, operations, and strategy to break down how to understand modern warfare.

Paragraph Summary

Based on a conversation with a military analyst on the Lex Fridman podcast, the article outlines three analytical levels for understanding modern warfare. The tactical level focuses on squad and platoon engagements, drone use, and daily battlefield developments; its information shapes leaders' expectations about bargaining chips, but what is truly worth observing is who is adapting and who is falling behind. The operational level is conceptually contested within military circles; its substance is the complex planning of intelligence, logistics, firepower, and multi-unit coordination, and it serves as a bridge. The core of the strategic level is the "theory of success"; what most reveals intentions is often what is chosen not to be done, and strategy must rest on assumptions that can be revised. The article concludes by pointing out two typical failures of disconnect between tactics and strategy, emphasizing that mutual verification across the three levels is what makes for effective judgment.
