space crusade marines could have assault cannons, second from the right is an assault cannon. also storm bolters in inquisitor arsenals are probably not astartes grade

Now you are trying to mix TT and an RPG. Those are WAAAAY older anyways and the new rules realize that doing that outside TDA is not feesable. Show me a current, non-modded model or stat-line or instance in official canon where a Space Marine grabs up an Assault Cannon in one hand, AND ONE HAND ONLY, and I would allow it.

As for Storm Bolters fired from an Arm Mounting, that's interesting but I think the main reason is that only high level people are afforded the ability to bring THAT kind of destruction. It's a point of respect and honor of their station. If it wasn't then why doesnt EVERY Space Marine get deployed with a gauntlet mounted Storm Bolter?

Personally, I'm not seeing why most people don't just allow the arm mounting of basic weapons. Its not like the free hand makes that much of a difference. They're already spending requisition on this.

I mean, it halves the weapons range, which is fair enough. Really all it does is make the player feel cool, and maybe not have to say "And I quick draw my melee weapon while dropping my bolter on its sling."

Its not like they can hold storm bolters in their hands, and have wrist mounted storm bolters, and fire full auto with all four weapons. Pretty sure a hand can only operate one weapon when dual wielding, so at most it will only be two weapons.

Fluff wise, yes, some may consider the known examples of this as being "relic" quality, but really, maybe its rarity is just because its generally waste of time? I mean really, what is a player getting out of this that would actually be good to employ in any sort of large scale manner? I imagine Grey Knights use this style as their force halbreds probably require two hands to wield properly. And Calgar is effectively using two bolters as a storm bolter, on top of power fists, all of which are at pretty awesome craftsmanship. To even copy those in DW terms is going to be something around a 70+ requisition weapon system. Why employ a higher cost weapon system when just a standard bolter is effectively equal.

Heavy weapons are obviously right out, and should never be considered for arm mounting. Unless of course it is immediately followed by the GM throwing the case of his DW CE at the munchkin.

On a totally unrelated side note, has anyone ever considered that a terminator can probably equip and fire 2 assault cannons without actually breaking any rules?

Part of the purpose of roleplaying is maintaining the atmosphere of the game, and if everyone could just take such things then why dont they? Why not make them standard issue?

On you unrelated note....you are technically right. As far as I can see there is no limitations on bringing two Assault Cannons with TDA but you still could only fire one AC, even if you consider the Full Auto as a half action due to the suspensor systems. So it's a waste of Req when you can take a melee weapon with which to defend yourself in CC and have the ability to handle things.

Why only fire one? The two weapon shooting rules don't state weapon class as a restriction for shooting both weapons on full auto.

Also, my point was that arm mounting is largely inferior for basic weapons, and not worth the cost on a larger scale. I was trying to say that it may very well be possible for entire chapters to employ arm mounting, but don't actually do it because it is not useful.

But you know there are people on this forum right now, you know who you are, thinking "But I could use vox operated wrist mounts and the rules don't say I can't!"

I have indeed thought just this. But I thought "Hmmm, I could mount an Assault Cannon AND a Heavy Flamer on TDA..."

Should have known to look up Brimstone from Warseer.

Of course, there's a reason GW never made any minis based on those concepts.
