It is clear. Vehicles may auto-break from CC. There are no other stipulations. It matters not whether tangle chains are being used.
Until new rules come out that supersede and/or clarify this, please, play it this way.
Due to some recent dissagreements on the game board I would like to take this one up again.
I did use the imperial Tangel chains to keep an Orca from flaming out my entire army. Since the orca is only size 3 and not a flyer I beleve they shuld be able to hold it (since the rules do not state otherwise, and the chain say "can not break away").
Logic, alone, says that this is just not so. Size is not the issue. Do you think that an ordinary mortal (or tangle chain-equipped Nepharite) could hold onto an Orca? While this is a game based upon science fiction and other-wordly beings, even the rulebook, itself, says to use common sense where issues such as this arise. An Orca is Size 3 based not only on it's physical height, but mass and girth, as well. A Vulkan is Size 3, too; however, it is not a vehicle and is subject to the chains. A Behemoth is not a vehicle, is the largest Size possible, and is, actually, subject to the chains, by the current rules. Granted, it doesn't make much sense that a Behemoth should be subject to the chains, but, I have, also, lost my Behemoth to Brass-knuckle-equipped Free Marines, too!
If it is the official ruling you seek, it is in the first line(s) of this post, and it is in the rulebook, also.
Game on!
