Operations is the middle layer of military analysis, below strategy and above tactics. Operations concerns the movement of forces (often over multiple lines of advance to fully utilize the transportation network available) and their logistical support. Fundamentally, operations are about getting forces to the objectives specified in your strategy with sufficient supply to sustain themselves, so that once there they can employ your tactics to achieve victory. The specific task of crafting operations which will achieve a set of strategic objectives is called “operational art” in US doctrine. Operational failures typically manifest as logistics and maneuver failures – particularly operational plans with unreasonable timetables – both of which have been particularly in evidence in the initial Russian invasion [of Ukraine in 2022].

Strategy is the upper layer of military analysis. Fundamentally strategy concerns the identification of final objectives, the way those objectives can be achieved and the resources to be used to achieve those objectives; these three components of strategy in US doctrine are termed “Ends, Ways, and Means” respectively. Strategy is thus the “big picture” thinking behind an action, including the decisions to both commence hostilities and end them.

Tactics are the lowest layer of military analysis. Tactics concern the methods to be used to win battles. Things like flanking, suppressive fire, ambushes, etc. are tactics. A military’s tactical system is often spelled out in doctrine. In theory, operations is designed to deliver forces to battles in such a way (positioning, comparative force, etc.) that their tactics can win those battles, while strategy should aim to ensure that winning those particular battles will achieve the desired political end (whatever concessions are desired). It is important to distinguish actions which are strategy (designed to directly produce a desired end to the conflict) from those which are merely tactical (designed to achieve a local success or advantage in a given engagement). It is important when assessing failures in war to distinguish between strategic failures (typically a failure to come up with realistic goals and the means to reach them), operational failures (e.g. logistics failures or unreasonable maneuver timetables) and tactical failures (e.g. failure to use combined arms effectively).
