The advent of accurate, long-range rifle fire, repeating rifles, and machine guns necessitated highly dispersed combat formations. This, coupled with radio communication, permitted relatively small numbers of men to have much greater firepower and combat effectiveness than previously possible. Companies, however, continue to remain within the general range of 100–250 members, perhaps validating the premise that humans fight best (as well as live, work, socialize, play, etc.) in organizations of around 150 members, more or less.
