Hussar Squadrons were armoured bike squadrons, used by the Space Marine Legions and served as an auxiliary force to formations of heavy infantry.

轻骑兵中队是装甲摩托中队，由星际战士使用，并作为重步兵编队的辅助部队。

The Hussars screened the heavy infantry's advance and pursued the foe once the infantry's volleys of boltgun fire set them to flight. They could also be used to mount an assault into the enemy, to buy their Battle Brothers time to take up positions, before retreating back to safety. Only the most steadfast and disciplined of a Legion's assault cadre were assigned as Hussars, though. They were warriors that could be relied upon in the heat of battle and those that excelled were amongst the elite of their Legion. So much so, that many Legionary officers had once served within the ranks of the Hussar Squadrons.

轻骑兵掩护了重步兵的前进，并在步兵的枪炮扫射使他们逃跑后追击敌人。他们也可以用来攻击敌人，在撤退到安全地带之前，为他们的战斗兄弟争取时间来占据阵地。不过，只有军团突击队中最坚定、最有纪律的人被指派为轻骑兵。他们是在激烈的战斗中可以依靠的战士，那些表现出色的人是他们军团的精英。如此之多，以至于许多军团军官曾经在轻骑兵中队服役。
