This thread will be dedicated to facts and estimations regarding the military strength of the many houses in Westeros. Books, TV shows, games and even personal estimations (if based on confirmed information; see my House Manderly estimate for example) are valid. This opening post will be consistently updated if new numbers that seem correct are added by other forum members. Great Houses are not listed, as they command all other Houses in their region.
