Melee infantry unit equipped with jump packs to overcome terrain obstacles.
The howl of jump pack turbines heralds the meteoric descent of the Assault Marines. Plunging from the sky with bolt pistols blazing, they slam into their foes like a hurricane of destruction. Screaming victims are thrown to the ground, bodies crushed beneath ceramite boots, chests ripped open by snarling chainswords. Within moments the killing is done, and the Assault Marines bound onwards, leaving behind them a ragged wound torn in the enemy's battle line.
