Trash unit

The trash units are cheap units that costs no gold or a rare resource. In all games of Age of  Empires series and Age of Mythology, there are several units that are considered " trash units". These units have some advantages as they can be massed easily and are for the most part they are useful for defend a location or counter certain enemy units. Most of the trash units are weak compared to a standard unit equivalent. The term " trash" refers to the fact that most of these units are made up from the resources surplus ( that in most cases are Wood and Food in all the games)

When a player is using trash units is expected that he or she is trying to overwhelm their opponents with quantity instead of quality of units, in other cases trash units are used as dummies
