How are Reinforcing Troops affected by the defending City?
A great way to assist an Alliance member in battle is to send an army to reinforce them.
Reinforceing Troops cannot be used on attacks by the defending city and are only used for defensive purposes. If the defending City is attacked while your Troops are still reinforcing, then only the defending player will receive a Battle Report. However, reinforcing Troops can be viewed in the allied player’s Embassy.
Please note that reinforcing Troops do not use your Research levels and instead reflect the Research of the player they are defending. These Troops are also fed by the defending City but if this City runs out of Food, the reinforcing Troops will return to your own City.
