A turning movement is an attack that avoids the opponent's strength by going around it — not necessarily to hit the flank, but to threaten something the opponent must protect (rear, supply, capital), forcing them to abandon their position or split their force. The defender faces a dilemma: hold the front and lose the rear, or turn to face the new threat and expose the front. Either way, their prepared position becomes irrelevant.
The concept is military (e.g. Sherman's march, the German sweep through the Ardennes in 1940), but it applies wherever you can achieve your objective by going around the opponent's main strength and threatening something they cannot give up. In business that might mean entering a segment they do not defend well, attacking a dependency (supplier, channel, standard) they rely on, or redefining the contest so their advantage no longer applies. The strategic question is: where is their "front," and what would force them to turn?
Use the model when the opponent is strong in a head-to-head fight and when you can create a threat to something they value more than the current battlefield.
Section 2
How to See It
Turning movement reveals itself when one side achieves leverage by threatening a target the opponent must protect, rather than by defeating the opponent's main force directly. Look for: moves that bypass the obvious point of competition; the opponent reallocating force or attention to a new threat; and the original "front" becoming less relevant. The diagnostic: did we win by going around, or by going through?
Business
You're seeing Turning Movement when a company enters a market through a segment or channel the incumbent does not prioritise — e.g. SMB when the incumbent focuses on enterprise, or direct-to-consumer when the incumbent is locked into retail. The incumbent's strength is elsewhere; by the time they turn to respond, the entrant has established position.
Technology
You're seeing Turning Movement when a product or platform wins by making the incumbent's moat irrelevant — e.g. cloud vs on-prem, or a new interface that bypasses the old integration layer. The fight is not "better product in the same category"; it is a different category that turns the incumbent's position.
Investing
You're seeing Turning Movement when a thesis depends on a company succeeding in a way that bypasses the main competitive battle — e.g. winning in geography A while the leader is focused on B, or winning on a different dimension (e.g. ease of use) that the incumbent cannot easily match without turning their whole strategy.
Military
You're seeing Turning Movement when a force moves around the enemy's prepared defences to threaten their rear, supply lines, or capital. The defender must abandon position to respond or risk losing what they cannot replace. The movement "turns" the enemy out of their strongpoint.
Section 3
How to Use It
Decision filter
"When the opponent is strong head-on, ask: what do they have to protect that we could threaten by going around? Can we force them to turn — to abandon their strong position or split their force — by creating a threat elsewhere? If yes, design a turning movement instead of a frontal assault."
As a founder
Do not attack the incumbent where they are strongest. Find the segment, channel, or job-to-be-done they under-serve or ignore. Win there, then expand. The turning movement is "we are not fighting for the same customer you are defending; we are winning the customer you are not defending, and that will eventually turn your position." The mistake is charging the front. The second mistake is assuming the incumbent will not turn — they will, once the threat is real; your job is to be entrenched before they can respond.
As an investor
Assess whether the company's strategy is a turning movement — winning where the incumbent is weak or not looking — or a frontal assault. Turning movements can succeed with less resource because they avoid the opponent's strength. The risk is that the incumbent eventually turns and brings force to bear; the company needs a plan for that moment (moat, speed, or next turn).
As a decision-maker
When you are the defender, watch for turning movements: where could the opponent go around us and threaten something we must protect? Defend the rear as well as the front, or accept that you may be turned. When you are the attacker, map the defender's center of gravity — what, if threatened, forces them to move? That is the objective of your turning movement.
Common misapplication: Confusing a turning movement with a flanking attack. Flanking hits the side of the force; turning movement threatens something behind or beyond the force (rear, supply, capital). Turning is about forcing the opponent to abandon position, not just hitting them from the side.
Second misapplication: Assuming the opponent will not turn. They will, once the threat is credible. The turning movement buys time and forces them into a worse position; it does not eliminate the need to win the subsequent fight. Plan for the counter-turn.
Amazon repeatedly used turning movements: books to get into e-commerce while physical retailers defended stores; AWS to get into enterprise while incumbents defended on-prem; Prime to make delivery and convenience the battlefield where traditional retail was weak. Each move went around the incumbent's strength and threatened a position they had to protect. The lesson: find the axis that turns the opponent's position, then commit.
Netflix turned Blockbuster by making the battlefield "selection and convenience" instead of "store footprint." Blockbuster's strength was retail presence; Netflix bypassed it with mail and then streaming. By the time Blockbuster tried to turn (late move into streaming), Netflix had entrenched. The lesson: redefine the contest so the incumbent's strength is the wrong thing to defend.

Visual Explanation
Turning Movement — Bypass the front; threaten the rear. Force the defender to abandon position or split force.
Section 7
Connected Models
Turning movement sits with flanking, center of gravity, and leverage. The models below either explain the manoeuvre (flanking, choke point), the target (center of gravity), or the advantage (OODA loop, indirection).
Reinforces
Flanking
Flanking is attacking the side of the opponent's force. Turning movement goes further: it threatens the rear or a vital objective. Both avoid the front; turning movement forces the defender to abandon position. The reinforcement: when the front is strong, go around — flank or turn.
Reinforces
Center of Gravity
The center of gravity is the source of the opponent's strength — the thing that, if lost, collapses their position. A turning movement often targets the center of gravity or something that protects it (e.g. supply, capital). The reinforcement: identify the center of gravity, then design the turn to threaten it.
Reinforces
OODA Loop
Turning movement works when you move faster than the defender's OODA loop: you reach the rear before they can reorient and respond. Speed is what makes the turn decisive. The reinforcement: compress your OODA loop so the defender is still orienting to the front when you are already at the rear.
Leads-to
Leverage (Physics)
Leverage is applying force where a small input produces a large output. Turning the opponent out of position is leverage: you threaten a small (or distant) point and force a large reaction. The connection: the turn is the lever; the defender's dilemma is the output.
Section 8
One Key Quote
"Appear where the enemy cannot defend; strike where the enemy is unprepared."
— Sun Tzu, The Art of War
The turning movement is exactly that: appear at the rear (or the segment, or the dependency) where they are not prepared, because they were defending the front. Strike there, and they must turn — and in turning, become vulnerable.
Section 9
Analyst's Take
Faster Than Normal — Editorial View
Do not fight the incumbent where they are strong. The front is their moat, their brand, their distribution. Find the segment, channel, or job they under-serve. Win there first. That is the turning movement: we are not competing for the same customer yet; we are building a position that will eventually force them to turn.
Speed matters. The turn works because you reach the "rear" before they can react. If you move slowly, they will reinforce the rear or turn in time. Compress the time between "we are going around" and "we are entrenched." Speed is what makes the defender's dilemma acute.
Plan for the counter-turn. Once you threaten something they value, they will respond. They may abandon the front and concentrate on you. Your advantage is that you chose the ground and the timing. Be ready to win the fight when they turn — or to turn again (next segment, next geography) before they can concentrate.
The "rear" in business is often a dependency or a segment. It is not always geographic. It might be a supplier, a channel partner, a customer segment they ignore, or a standard they rely on. Map what they must protect; that is the list of possible turning objectives.

Test Yourself
Is this mental model at work here?
Scenario 1
A startup targets SMB customers while the market leader focuses on enterprise. The startup gains share in SMB; the leader eventually launches an SMB offering but is two years behind.
Scenario 2
A company attacks the incumbent head-on with a better product in the same category and wins 30% share in two years.
Scenario 3
A military force moves through difficult terrain to threaten the enemy's supply depot; the enemy abandons its fortified line to defend the depot.
Scenario 4
A platform wins developers by offering better tools and revenue share; the incumbent's strength is end-user base. Over time, developers bring users to the new platform.
Section 11
Top Resources
Turning movement and manoeuvre warfare appear in military history and strategy. These resources connect the concept to business and competition.
Clausewitz on the "center of gravity" and the need to strike at the source of the enemy's strength or the means that sustain it. Turning movement targets the rear or dependencies that support the front.
Rumelt on leverage and "pivot" — applying strength against weakness. Turning movement is a form of pivot: you pivot the contest to ground where the opponent is weak.
Thiel on competition and monopoly. "Competition is for losers" aligns with turning movement: do not compete head-on; find the space where you can win without fighting the incumbent's strength.
Christensen on disruptive innovation: entrants often win by serving non-consumption or the low end — a turning movement that goes around the incumbent's focus on sustaining the high end. The incumbent is "turned" when the disruption reaches the mainstream.
Leads-to
Choke Point
A choke point is a narrow passage or dependency the opponent must use. Threatening a choke point (e.g. supply, distribution) can be the objective of a turning movement: they must defend it or lose the war. The connection: the "rear" you threaten may be a choke point.
Tension
Indirection
Indirection is achieving a goal by acting on something else — e.g. winning a customer by winning their supplier. Turning movement is indirection in space: you win by threatening something other than the main force. The reinforcement: do not attack strength head-on; attack through a turn or an indirect target.
