Artemis Team was the first Thunderfist squad created. The team, consisting of Private McManus, Private Ruiz, Sergeant Hawk, and Lieutenant Kurosawa, and the Commander (Lone Wanderer) were the first ones to receive Thunderfist Armor. Their mission was to head for the Moon in order to retrieve a functioning generator to reverse engineer. When the generator they found exploded, they fled into a teleporter room that sent them to an underwater alien base that would one day become Poseidonis.
To the latest version of the mod, the Commander and Private Mcmanus is all thats left of Artemis Team due to the fact Sergeant Hawk and Private Ruiz are both dead while Lieutenant Naoko is in a coma following the events of the Brotherhood Commandos kamikaze bombing.
