Glade Defenders is the attrition-and-recursion Sylvaneth battle formation for AoS 4th edition, designed to reward an army that expects to lose units and bring them back. This is original commentary rather than official rules text; verify the exact trigger and bonus in your current battletome.

What does the formation do?

It grants a chosen unit additional melee attacks based on how many friendly Sylvaneth units (and Wyldwoods) were destroyed the previous turn. In effect, every loss you take powers up a survivor, so the formation turns the army's natural attrition and resurrection loop into an offensive engine: the more the enemy kills, the harder your remaining trees swing back.

Who does it suit?

Players who embrace the recycle-and-return identity of Sylvaneth and run bodies they are happy to trade, such as Dryads and Revenants, then raise them again. It suits a grinding, resilient playstyle over a fragile alpha strike.

Key units

Dryads and Revenant infantry as expendable, recyclable bodies that feed the mechanic.
Kurnoth Hunters as the survivor you want to hand the extra attacks to.
Heroes and traits that resurrect units so you keep the loop spinning.
Awakened Wyldwoods to enable the healing and resurrection that make trading worthwhile.

When should I pick it?

Pick it in grinding matchups where combats are attritional and you expect to lose and regrow units repeatedly. It is weaker if you are trying to play a cagey, casualty-averse game, since the bonus only pays off when things are actually dying on your side.

Common questions

Does Glade Defenders reward losing units?

Effectively yes. The formation converts your casualties from the previous turn into extra attacks for a surviving unit, so combined with the army's resurrection traits, trading bodies becomes a source of offensive power rather than a pure loss. Confirm the exact scaling in your current book.

How does it combine with the army's resurrection?

Very naturally. Traits like The Land Awakens and Endless Growth bring units back, so you can afford to lose bodies, cash in the extra attacks via Glade Defenders, and then regrow the fallen units to keep contesting the board. It is the most synergistic formation for a recursion-heavy list.
