Jump Pack - Jump Pack Operation: 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.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.Though Jump Packs are an ancient technology that has served the Adeptus Astartes for millennia, the Space Marine Chapters of the present 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.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 Land Speeder 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.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.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.
