You can uproot your defenses (Mortar, Cannon, Archer Tower, etc.) to the battle!
For example you will tap on a defense. Tap uproot and it will be gone but it will be part of the troop inventory. So if you start a battle you will see that defense at your troops bar. Drag from the bar and release if you already have a suitable place to put. If the defense is destroyed it will recover as if someone raided your village. You cannot still donate defenses at the clan.
