(From sticks and stones to advanced projectiles capable of annihilating the entire planet, warfare has evolved along with civilization.

The advent of technology was one pivotal aspect that forever changed how wars were fought from ancient times to the modern era—and it will be the same factor that will keep it in constant development as humans strive to gain the upper hand over each other.

Certainly, aggravating skirmishes did not begin during the rise of Mesopotamia, but it was during this period that traces of the “earliest armies at war” were first uncovered by archeologists. Not to dwell much on that department, in short, men have always fought one another, whether for basic necessities and resources to plain greed for control and power. What makes it different from one era to another is the advancement of tools and tactics.

In ancient civilization warfare, with the absence of long-range weapons, formidable tanks, and destructive missiles, warriors relied so much on hand-to-hand combat and wit to outsmart enemies, which would become the centerpiece of the evolution of military tactics—branching out as people who fought for dominance and power generation after generation aimed to conquer effectively and efficiently without losing so much of their own. Here are three ancient military tactics that helped shape warfare across centuries.

Battle Formation

The earliest, most popularly known battle formation that originated in the ancient period was the phalanx, “a block of heavily armed infantry standing shoulder-to-shoulder in files several ranks deep,” which was first employed by the ancient Sumerians and enhanced by the ancient Greeks. For thousands of generations, the formation evolved and even survived well into the gunpowder era, with most historians viewing it as an important foundation of the European military.

A standard phalanx formation for the Sumerians composed of six men, with the first line carrying large, rectangular shields, while the rest of the troops bore heavy pikes and battle axes. Greeks, on the other hand, were “equipped with a round shield, a heavy corselet of leather and metal, greaves (shin armor), an 8-foot pike for thrusting, and a 2-foot double-edged sword.” This was further improved by Philip II of Macedonia and his son, Alexander III (famously known as Alexander the Great), adding more mobility and intimidation.

Alexander’s phalanx arrangement, for example, normally consisted of 16 men, with each soldier armed with a 13- to 21-foot spear (also called sarissa). During battle formation, the first five men on the line held their spears horizontally while the rest presumably held theirs vertically or rested on the shoulders of those in front. To amplify the formation, each side of the phalanx was the light infantry, a unit of archers, slingers, and javelin men, and the heavy cavalry, who were tasked with protecting the flanks and targeting the weak points of the enemy. In addition, a squadron of light horses was mobilized for scouting and skirmishing against loose enemy units attempting to outflank.

The Romans would later discover the effectiveness of the Greek’s phalanx and adapted the formation, adding their touch by using thrusting spears. Shortly after, however, they ditched it for a more flexible three-line legion, which boosted the Romans in their conquest to conquer the world.
