This suggestion is about, as the obvious title suggests, the implementation of desertions among the ranks of your army of hired units. they could be turned of like invasions or orc skirmishes.
Desertion:
it would happen when there are more enemies than allies near by, and would have a different chance of occurance depending on the unit in question.When the unity deserts it stops being hired and runs away like gollum does when hit. The categories of units are:
Cowardly: deserts if there is the same amount of allies and enemies.
Fearful: Deserts if there is twice the amount of enemies than allies
Brave: Deserts if there are thrice the amount of enemies than allies
Very Brave: Deserts if there is Four times the amount of allies nearby.
Heroic: Deserts if there is eight times the amount of allies attacking
Legendary (Insane): Never Deserts
Here are a few examples of units:
-Half-Troll(civillian),Angmar, Dol Guldur, Gundabad and Isengard orcs: Cowardly
-Black Uruks, Gundabad Uruks, Half-Troll Warriors and Uruk-Hai: Very Brave
-Dunlending: Fearful
