===Request Army===
You can spend allegiance to ''borrow an ally or vassal's [[army]]'' for a set number of turns, after which the army (or what's left of it...) will be returned to the ally's control. This can be extremely useful, but costs a lot of allegiance. Restrictions: they need to have an army, and their faction leader's army cannot be requested.

As of [[update 2.4.0]] there is currently an exploit in this mechanic:
*A [[hero]] with the ''immortal'' skill is in an ally's army.
*You borrow the army.
*The hero is wounded while under your control.
*The hero will go into your own hero pool, to be recruited.
*You have essentially stolen that hero from your ally.
*This allows you to get heroes which are not from your race and keep them.
