Vehicle cover saves

Is the rule about going to ground improving your cover save by 1 only relevant for going to ground? Can a cover save be improved another way, for example if a Raider moved flat-out and was obscured by models? Or had a flickerfield? I'm guessing not, as that would confer a 2+ cover save, but thought it was worth checking!

Vehicles can't go to ground. So this rule doesn't apply, but if a vehicle is inside better are terrain, it can use this cover save, but this would be pretty rare, since 3+ terrain isn't realy common.

If there was a special rule, that would improve a cover save, vehicles could benefit from it, but I don't know any.

Ah ok - I know they can't go to ground, but I thought it might work in the same way as going to ground in that it improves your save by one. I shall just stick to being super speedy!

Oh, now I get what you meant. If you have multiple saves, be it armour, invulnerability and/or cover, you always use the best one, and only this one.

You can get a 3+ cover save, but it has to be that the model shooting (meaning the enemy's) can see your vehicle, but not a part that is in the arch it is firing at. Its complicated, but does come up (like a ML Dev being in your front arch, but only seeing a wing of a venom, not part of the front hull) Its easier to decern with Imperium vehicles, so we are against left out of luck because we are on flying stands and not boxes...
