The term “Recon Unit” refers to any Unit that can be sent on Recon Missions.
Recon Units can be used to assess the strength of enemy forces at Bases, Annexes, Resource Caches, Alliance HQs, and Black Sites.
Recon Units have no Offensive power, meaning they cannot be sent on Offensive missions alone. However they can be used to improve Carrying Capacity on Raids, and also as extra Defensive force.
