Evolution of Infantry Formations

Infantry formations have evolved to adapt to changes in warfare, technology, and tactics. Early armies used dense formations like the phalanx for protection and collective strength. As firearms became prevalent, lines and columns were adopted for better firepower and maneuverability. In the 20th century, with the advent of mechanized warfare, formations became more dispersed and flexible, focusing on mobility and the ability to respond to dynamic battlefields. Today, infantry units emphasize coordination with technology and air support, using smaller, more agile teams to engage effectively in diverse environments.
