A work in progress is being carried out on this page by Auctorius,
Two spear fighters are the default city defense if not specified otherwise. Furthermore the spear fighter with its short recruitment time and the low training cost is great as a "trash unit". So if a quest tells you to delete units normally the spear fighters are the go to, if you don't want to loose any valuable units. This is very helpful in special events.
