Ask this placement to go and take something for itself and it stalls. Ask it to protect somebody it loves and the same person becomes immovable, articulate and quietly frightening. Mars in Cancer routes action through attachment, and the difference in available force between those two situations is the whole story of the placement.
Mars is in Fall in Cancer. In practice that means the function is running through material it was not designed for: direct assertion has to pass through mood, timing and consideration of who will be upset, and by the time it comes out it has changed shape.
None of that removes the strength. It relocates it, from confrontation to endurance and defence, and it makes the trigger somebody else's welfare rather than your own advantage.

Force that has to be provoked
You do not initiate easily. Wanting something is not enough to move you; the internal question of whether it is your turn, whether the moment is right, whether somebody will mind, arrives first and usually wins. Then a threat appears to a person, a home or a piece of work you have made yours, and the hesitation vanishes completely. Watching this happen is startling for people who had you filed as mild, and it is the most consistent report from anyone who has known this placement for long: the mildness is real, and it is not the whole inventory.
Anger that goes sideways
The direct expression is blocked, so the feeling finds indirect routes: the shortened answers, the sudden coolness, the tone that says nothing is wrong in a way that makes clear something is.
This is not manipulation, though it is regularly read as such. It is what assertion looks like when it cannot go out in a straight line and will not be dropped, and the more time passes the less anyone can identify what started it — including you, since the original grievance has by then been joined by three others of the same shape.
Defence over attack
Given a cause with a person inside it, this is one of the most persistent placements there is. You will do the unglamorous protective work for years — the funding fought for, the child defended, the colleague nobody else stood up for — long after a more explosive drive would have exhausted itself. The pattern is worth recognising in yourself, because it also means your own interests tend to get represented last, and often only when somebody else frames them as being on their behalf.
Mood as the throttle
Output here is tidal. A settled week produces steady, careful, surprisingly tough work; an unsettled one produces very little, and no amount of scheduling overrides it. That is the practical cost of the placement, and it is easier to work with once you stop treating it as a discipline problem. People with this Mars generally do better protecting the conditions — sleep, home, who is in the room — than trying to force output out of a bad stretch.

FAQ
Mars in Cancer: common questions
That your drive is filtered through feeling and attachment before it acts. Direct self-assertion is expensive here, while protective effort on behalf of someone you love is close to unlimited. The placement is strong in defence and endurance and weak at cold, immediate confrontation, which is a different profile rather than a smaller one.
It is a description of the conditions the function has to work in, not a verdict on the person. Assertion here runs through mood and loyalty instead of going out straight, so it arrives late and indirect. What it gains in the same movement is staying power: this Mars keeps fighting for something long after a more direct one has lost interest.
Because the confrontation route is closed and the feeling still needs somewhere to go. Withdrawal reads to you as the least damaging option available, which is honest, and to the other person as a punishment, which is why it usually escalates the thing you were trying not to escalate. Saying the small version early avoids most of it.
Badly in the moment and well over time. Direct challenge in a meeting is unlikely, and the reaction often arrives hours later in written form, much better argued. Long, patient, quietly stubborn campaigns suit this placement far better than confrontations, and it wins a surprising number of them by simply not going away.
Because the trigger for this drive is protection rather than gain. Someone else's need supplies a justification that your own wanting never quite manages to, so the force is available instantly and without guilt. Many people with this placement only get their own interests defended by finding a way to frame them as someone else's.
