The 2nd edition of the Dark Heresy RPG Core Rulebook has many pages worth of rules for vehicles. It then backs this up with the stats for a car, a bike, and a tank (technically an APC I suppose, but still). There are rules for walkers, skimmers etc, but no stats for them.
Having looked through several vaguely related rulebooks, there are more vehicle stats. None seem to be perfectly meant for use in Deathwatch v2, with issues such as the rarity stat being lacking, and potentially balance issues bringing vehicles from high powered games like Deathwatch into DH.
Has there been any official confirmation about what sources (Only War, Deathwatch, Rogue Trader, other) 'are official' for use in DH, or rules for adapting these sources to DH2?
