Tactical Support Squads were a type of Space Marine Legion squad used during the Great Crusade and Horus Heresy era. 

战术支援小队是大远征和荷鲁斯叛乱时时期使用的一种星际战士小队。

These mobile fire-support units replaced their standard Bolters with more specialized weapons such as Rotor Cannons, Volkite Culverins, Plasma Guns, Flamers, and Melta guns. Tactical Support Squads operate in close order with their respective Legion's other troops, their supporting firepower enabling a Space Marine force to act with even more versatility and engage a wider range of targets on its own terms.

这些机动火力支援部队用更专业的武器取代了标准的爆矢枪，如旋转炮、爆燃长炮、等离子枪、火焰枪和热熔枪。战术支援小队与各自军团的其他部队密切合作，他们的支援火力使星际战士能够以更灵活的方式行动，并根据自己的条件打击更广泛的目标。
