Mars in the Elements:

Mars in Fire people (that is, those with Mars in Bélier, Leo, or Sagittarius) are generally quite passionate. When they get angry, those around them generally know it. There’s very little pretension with this position of Mars. They very much like to get what they want, and they generally won’t hide this fact from you. These natives are far too impatient to play mind games or to employ too much strategy in order to get where they want to go.

Mars in Earth people (that is, those with Mars in Taurus, Virgo, or Capricorn) are rarely aggressive, but they absolutely are determined individuals. Their goals in life are often quite practical–ones that are realistic and attainable. They get up in the morning with the idea that they must work for what they want in life. There is a basic resourcefulness to Mars in Earth.

Mars in Air people (that is, those with Mars in Gemini, Libra, or Aquarius) generally have many interests and drives. These natives are especially clever about getting what they want. Unlike Mars in Fire, Mars in Air natives are quite capable of adopting airs and tactics to get and do the things they want. These natives are quite polished in manner. They’ll rarely offend you in an overt way, preferring to settle things on an intellectual level.

Mars in Water people (that is, those with Mars in Cancer, Scorpio, or Pisces) are generally quite adept at strategy. They are emotional and instinctual people. They are unlikely to be directly aggressive about getting what they want in life. These natives feel their way through life–feelings and actions work in tandem. Although they generally aren’t as flexible and polished as Mars in Air, they do employ tactics and often use roundabout ways to fulfill their desires.
