The soilder ! Mars.
What you think where a soldier can be at his best?
I think in following places:
In 10th house(Kuldeepaka Rajyoga): In kalapursha kundali, 10th house is Capricorn. Mars gets exalted in Capricorn, because Capricorn represents: Forest, workplace, battlefield, knee etc. So, a soilder can do his best here and also it represents knee, it is the largest joint of our body and we walk with help of knee etc. (Jupiter gets debilitated in Capricorn because of these things, Jupiter is guru and wisdom, nothing to do with physical power, action etc)
4th aspect of mars will be on ascendant:makes native strong, disciplined, learns frommistakes, ambitious.
7th aspect on 4th house: native will care about his/her family, protect his/her family, having good house, relationships with mother can be in question.
8th aspect on 5th house: will destroy his/her child’s enemies, obstruction in education will be destroyed, also gives education in technical field and also having adventures desires in life.
Note: I remember that Bollywood actor Salman Khan have exalted mars in 10th house, he is the most successful son of his father (Kuldepaka rajyoga)
In ascendant: Native will be brave, strong, courageous, dominating, can be soilder, engineer, doctor too
4th aspect on 4th house: learn lessons from family, strict mother, disciplined environment in family etc
7th on aspect on 7th house: try to dominate over others, spouse, courageous, good business skills, aggressive speaker, etc
8th aspect on 8th house: will destroy his/her problems, longevity is increased, surgeon etc
In 6th house: Destroyer of enemies and diseases, strong immunity, doctor, sports person, father can be in army.
4th aspect on 9th house: destroy enemies and diseases with the help of father, destiny, religious thoughts and courage too.
7th aspect on 12th house: will lend money to others, help people in hospital, jail etc
8th aspect on ascendant: will destroy bad qualities of native, makes very active, aware of his/her diseases and enemies.
Note: all these results are general, I have only given hints that how mars and his aspect will act different in different houses.
