Sometimes you may think a few extra troops would come in handy when defending your base. Well the good news is you can request some troops to be donated by your fellow alliance members. To do this all you will need to do is click on your Alliance Embassy and then tap Request troops.
This will give your Alliance members the opportunity to donate troops to your base.
And it may be nice every once and a while to return the favor to your Alliance members by donating troops to them. To do so start by tapping on the chat option on your screen.
After that you can click on the donations tab to see if anybody has requested troops.
Now just click the donate troops button to send troops on their way.
