Ultramarines Primaris Outriders 极限战士原铸先遣者

Outriders are most commonly used to advance ahead of the main lines and to guard the flanks of larger formations. In battle, they perform lightning fast hit-and-run attacks on enemy strongholds, and are employed to chase down any who would seek to escape. Their Raider Pattern bikes are equipped with frontal Bolters while they themselves wield Chainswords and Bolt Pistols. The bike incorporates advanced suspension units to tackle rough terrain. The performance of the bike is effective as long as the rider can dominate its bellicose Machine Spirit.

先遣者最常用于在主战线前方前进，并保护较大编队的侧翼。在战斗中，他们对敌人的据点进行闪电般的攻击，并被用来追捕任何试图逃跑的人。他们的突袭者型摩托配备了前部爆矢枪，而他们自己则挥舞着链锯剑和爆矢手枪。这辆摩托采用了先进的悬架装置，以应对崎岖的地形。只要骑手能够驾驭其好战的机魂，摩托的性能就是有效的。
