《Munitorum》节译：跳跃背包

Based on ancient STC technology, the jump pack is affixed to a warrior in power armour, drawing energy from the suit’s own power pack to augment its high speed motors. Intake vents on the top of the pack greedily suck in air to feed the jets, while the turbine blades expel a long plume of vapour. Even with the aid of the power armour’s energy coils the jump pack has its own fuel supply, such is the power required to send a fully armed and armoured seven-foot tall warrior into the sky.

跳跃背包是基于古老的STC技术制成的，它被附着在动力甲上，从动力背包中抽取能量以提升其高速马达（的推力）。位于背包顶端的进气口会贪婪地吸入空气，供喷气机使用，同时涡轮叶片会喷出一道蒸汽长柱。尽管有动力甲能量线圈提供协助，但跳跃背包也有自己的能量供应——这便是将一名全副武装的七英尺高战士送入空中所需的能量。

A jump pack is usually good for a dozen or so ‘jumps’ before it must be refuelled or discarded. This is usually enough to get a Space Marine into the fray, or allow him to descend from the sky, striking deep behind enemy lines. An empty jump pack can be a liability, and even with his prodigious strength a Space Marine can find it impedes his ability in combat. For this reason, the jump pack commonly incorporates a quick-release mechanism on the battle-brother’s chest plate. Keyed to his specific power armour gauntlet, it is a lock that can be opened with a touch, allowing him to shrug free of the pack in moments.

在必须重新加注燃料或被解绑摆脱之前，跳跃背包通常能进行12次左右的“跳跃”。这通常就足以将一名星际战士送入激战，或允许其从空中降落，对敌军战线后方进行深入打击。耗尽燃料的跳跃背包则是一件累赘，哪怕是拥有惊人力量的星际战士们，也会发现这件累赘妨碍了自己战斗能力。因此，跳跃背包上通常也被整合了一个位于战斗修士胸甲上的快速解脱装置。该装置与动力甲的某只手铠相连，星际战士轻轻一碰便能解开束缚带，片刻之内便甩掉跳跃背包。

Though jump packs are an ancient technology that has served the Adeptus Astartes for millennia, the Space Marine Chapters limit their use to specialist formations within each company. In battle, these Assault Marines are ideal for striking at the flanks of the enemy or hitting behind their lines. Many heretics and foul xenos have met their end at the hands of jump pack equipped Space Marines, their final moments watching transfixed as armoured warriors descend from the sky on shimmering vapour trails.

虽然跳跃背包是一项服务了阿斯塔特修会数千年的古老科技，但星际战士战团仅限各个连队中的专门编队使用它。在战斗中，这些突击战士是进攻敌军侧翼或袭击后方的理想选择。很多异端分子和恶烂的异形就是死于装备了跳跃背包的星际战士之手——在生命中的最后时刻，它们目瞪口呆地看着装甲战士拖着闪闪发光的蒸汽尾迹从天而降。

Jump packs are also used to make high altitude battlefield insertions, where Assault Marines will leap from Stormraven Gunships or other Space Marine aircraft, their packs slowing their fall at the last moment. Space Marines can also use their packs to leave battle in the same way, leaping up straight into the air and into hovering transports or even grabbing onto the side of a Landspeeder or Stormraven as it screams across the battlefield. In this way, a Space Marine with a jump pack can throw himself out into space in the upper atmosphere of a world, guide himself down through swirling clouds and enemy fire to come crashing to ground near a high priority target. Then, once he has destroyed his target with either a well-placed melta-charge or several blows of his chainsword, he can leap once more into the sky, vanishing into the fog of war before the enemy has even reacted to his arrival.

跳跃背包也适用于战场高空插入行动，在此类情况中，突击战士们从风暴鸦炮艇或其他星际战士飞行器中一跃而下，跳跃背包会在最后时刻减缓其降落速度。星际战士也能利用跳跃背包，用同样的方式脱离战斗——垂直向上跳入空中，进入悬浮着的运输机内，甚至是在兰德速攻艇或风暴鸦从战场上呼啸而过时抓住其侧面。凭此方法，装备了跳包的星际战士也能把自己抛到星球上层大气之外的太空中，引导自身穿过漩涡云层和敌人的火力，在某个高优先级目标附近落地。在用恰当放置的热熔炸弹或链锯剑的数次劈砍消灭目标之后，他就能再次跃入空中，在敌人对其到来做出反应之前，便消失在战争迷雾中。

Many Space Marine commanders personally favour the use of a jump pack, especially those that seek out personal combat with the foe. A jump pack allows such a hero to leap across the battlefield far faster than he could run, ensuring he is always in the thick of battle. Nowhere is safe from the Space Marine hero, and he can use his pack to leap up onto battlements, over massed enemy formations and past formidable trench-works with equal ease. If the hero can see his foe then he can reach them, and with a roared challenge can charge upon wings of smoke and fire.

很多星际战士指挥官自身也偏好使用跳跃背包，尤其是寻求亲自上阵杀敌的那些。装备了跳跃背包后，这些英雄能以远快于奔跑的速度跃过整片战场，确保自己总是位于战况激烈处。在这些星际战士英雄们面前，敌人没有可供安全躲藏之地，而且前者们还能用跳跃背包飞到战场上方，无论是躲开密集的敌军编队，还是穿过可怖的堑壕工事，都同样轻松。如果看到了自己的敌人，英雄们就会赶到其身旁，他们会怒吼着发出挑战，张开烟雾和烈火组成的双翼猛冲上去。

Jump packs are a symbol of the might of the Adeptus Astartes, and many are ornately crafted with intricate gilt-work or even unfurled wings. The sight of scores of power armoured giants arcing over a battle is an awe inspiring sight, enhanced by the image of glowing wings and billowing clouds of fire upon which the warriors seem to walk. An enemy witnessing such a grand and terrible vision can be left with no doubt he faces the Angels of Death.

跳跃背包是阿斯塔特修会强悍力量的一种象征，其中很多都被华美地镀金加工过，甚至带有展开的翅膀状饰品。数十名身披动力甲的巨人从战场上方沿弧线飞跃，这是一副令人敬畏的景象；而战士们张开发光的翅膀，似乎行走于滚烫火云之上的场景，更是加深了这种印象。当一名敌人目睹如此壮观且恐怖的场景时，毫无疑问，他将要面对的就是死亡天使。
