Micromanagement (known as Micro) is a strategy element that involves selecting specific types of units and using them carefully to execute specific maneuverings. It's a difficult but important skill to master, as it allows a player to greatly reduce their casualties and defeat their opponents with a minimally sized army. At all games it is an important skill, but particularly to civilizations that handle fast or tricky units (especially if they are fragile or easily countered, e.g. by spear/pike/bayonet units), such as cavalry, and to ones that possess unconventional traits.
