A '''Jump Pack''' is a back mounted device containing turbines or jets powerful enough to lift even a user in [[Power Armour]]. They greatly enhance a warrior's mobility by allowing him to travel quickly across the battlefield, making great bounding leaps over obstructions and launching himself into the melee of close combat. It's roaring engines allow a user to slow his descent when leaping from low-flying aircraft, allowing him to [[Deep Strike]] with relative safety directly into the fray. Any model equipped with a Jump Pack also counts as Jump Infantry.^1-p85
