Some Catachan units can be upgraded to Deathworld Veterans. The following rules apply to these units:
- Deathworld Veterans count woods or jungle terrain as clear terrain for the purposes of movement, including for advancing after an assault or falling back.
- Deathworld Veterans receive a 4+ cover save for being in woods or jungle terrain.
- Deathworld Veterans who don't move in the movement phase may see and shoot through 12" of woods or jungle terrain, rather than 6" as would usually be the case.
- Deathworld Veteran units may infiltrate as described on page 134 of the Warhammer 40,000 rulebook. They may only do this in missions that allow infiltration and only if they use their ability to infiltrate to set up or move into woods or jungle. They may only use this ability if on foot; players that have Catachan Rough Riders or Armoured Fist squads may not use them to infiltrate.
