How do you put reinforcements on the wall?

Lol I’ve been wondering the same thing!

 

If your troops are home (militia, guards, pugs, hunts, knights etc.) they will be on guard duty, defending your kingdom from attacks.

You can lend reinforcements to a clan member by tapping their kingdom in the realm view and navigating through the blue defend button menu.

You can hopefully get reinforcements by asking in your clan chat for them to “rein”/“RF” (reinforce) you. You would typically do this if you are being attacked.

Does that help?
