Thickets are static devices in the Reclamation Algorithm game mode of Arknights.
Thickets act as a source of 
Wood and harvested by having friendly units attack it, who attacks enemies over the Thickets, until their HP is depleted, at which the Thickets' HP is fully restored and it will have 1 that can be picked up by deploying an Operator adjacent to it, adding the Wood to their carry capacity which is equal to the Operator's block count and will be accounted for when the Operator is retreated. After the Thickets is harvested a certain amount of times, it will be exhausted and cannot be gathered from anymore (although the Wood it has can still be picked up).
Basic Harvesters deployed from Basic Gathering Hubs are more effective in harvesting Wood from Thickets than other resources.
