“Eos” is an elite unit of the Agurts 303rd Marines. Their name derives from the ancient tale of Eos, when the peninsula came under siege and civilians along the coast were called to arms. During the attack, a well known fisherman- Eos leaped into the stormy seas and severed the invading navy’s anchors, causing enemy ships to collide and sink in the storm. The story of Eos inspired the incorporation of local fishermen to form the region’s first amphibious force. Amphibious warfare have undergone great changes since the Gray Summer, troopships and aircraft carriers have limited effectiveness in coastal conflicts today. Missions must be carried out with a small but deadly group of soldiers. The Eos specialize in amphibious assault, armed with a diverse arsenal, these units are capable of destroying heavy fortifications and performing rapid assaults at the same time.

艾奧斯突擊兵隸屬於亞格斯第303海軍陸戰隊，這個名字源自一個公元前的故事：古希臘的沿海城鎮受到入侵，召集了一批漁民參與軍事行動。其中一名叫艾奧斯的漁民，勇敢地在風暴來臨前潛入海中，割斷了敵軍船隻錨繩，使他們在暴風雨中相互撞擊而導致潰敗。其後，古希臘軍隊開始組織漁民，建立了最早的「兩棲部隊」。 在兩棲登陸作戰中，運兵船或者航空器運載力有限，搶灘登陸時必須要用非常有限的兵力達成作戰任務。艾奧斯突擊兵會配備如火箭筒這類重火力武器，首先摧毀敵軍防禦工事或SA，然後用輕型武器裝備發起突擊。 蘇霏成年那天，鮑勃察覺到這個倔強的小女孩終於要踏上屬於自己的征途，便將自己那如同護身符般的橙色圍巾悄悄塞進她背囊的底層。
