Mark grasslands as no-go zone until further notice. Develop glands within warrior drones to produce paralytic agent to aid in combat. Paralytic agent is to be injected into foes via mandibles. Deploy regiment of 28 workers and 7 soldiers in tight formation to locate, secure, and retrieve food from forest. Set a portion of remaining worker drones to begin construction of tunnel from the central hive toward the forest; tunnel is to be braced with twigs gathered from last outing. Any techniques discovered or developed by drones during this undertaking should be documented for further review. Upon completion, tunnel should end in a hidden satellite access point to the hive. Store stones gathered from river until they can be used. Reassess current hive roster and available resources.
