Warfare
After the Dark Ages in ancient Greece, a new system of warfare evolved; weaponry, tactics, ideas and formations changed. Modified by Philip II and mainly by Alexander the Great after the Macedonians conquered Greece, this new age of warfare lasted until the rise of the Roman Empire, when new tactics and the legion formation became the general methods of battle. The new "breakthrough" in military affairs was due largely to a new type of formation of infantry men, or hoplites. This formation was called the phalanx. The hoplite was heavily armed; he was equipped with a round shield, a breastplate of metal and leather, a helmet, and metal shin protection called greaves. His two weapons were a double-bladed sword and an eight foot pike for thrusting. These men were much faster and more maneuverable then the old system of disorganized fighting, where heavily armed soldiers individually fought one-on-one with others (the leaders of opposing sides would search for the men with reputations to fight). The phalanx was held in solid ranks, and divided only by a center line and two flanking sections. The soldiers stood shoulder to shoulder in files about eight ranks deep. The men in the front line held their shield strapped to the left arm and the sword in their right hand, thus protecting the man on their left while being protected by the man on their right. There was little need for an officer corps; because the formation was not complex, the whole body moved as one unit to the sound of a flute. However, the phalanx did present weaknesses: because it was sometimes difficult to maneuver due to its "bulky" size, if penetrated by the enemy, it became little more than a hectic, disorganized mob. Also, men tended to drift to their right for the protection of the shield held by that man. The solution to this problem was to place the strongest and most adroit fighters on the right flank to keep the unit from drifting on a battlefield
