The Spirit is Aeon's scout. This scout is weaker in combat than the UEF T1 Land Scout, the Snoop, but is less expensive and possesses the ability to hover, enabling it to spy on opponents whilst hiding off the coast. It is also the fastest land unit with a speed of five. However, if your opponent is aggressive, they may attack the army with one of their own that isn't made up of scouts. In that case, your army will be slaughtered and the enemy will gain veteran xp. counter that scenario by self destructing the units so they don't become punching bags.
