Mars in the natal chart is the energy we use to achieve our goals. It’s how we go about getting what we want. As the composite chart is a chart of the blending of individual energies, the composite Mars shows how we act as a couple. It is the representation of the energy when acting in concert. When you present a “united front” in action, you do so from the position of the composite Mars.
Strategically, this increases your options. When planning how you will accomplish something, you go from having just one position, as an individual, to the choice from three: two individual Mars’ energies plus that of the composite. It’s a simple concept and one you see all the time. Couples divide up responsibilities regularly. He does the shopping while she does the cooking. Perhaps they clean up together, or perhaps they delegate the cleaning. This is part of what makes coupling such a grand, practical arrangement, when it works. You have more options. In this case, one plus one equals three.
The composite Mars is the midpoint between the two individuals’ placements. If both the individuals share a Mars sign, the composite Mars will, of course, be the same. However, each individual will have that Mars aspected differently in their chart, perhaps in different houses as well, and the composite Mars will present a third position. Most people just naturally fall into divvying up the responsibilities, but knowing all three Mars positions can pay off when you really need a job done right.
You’ve got an important job to do? Your mother is freaking out about the Christmas plans? The sewer line broke and they won’t send someone out till next week? Which Mars do you send out? Hers, his, go together? Don’t send a Libra Mars to do a Scorpio Mars’ job, and vice versa.
