Are vehicles any different than troopers when you check to see if they recieve cover? For example, if an AT-RT is behind a barricade, does it recieve cover? If it is almost completely obscured by another terrain element, does it recieve cover?

Generally speaking, a unit only receives cover if the piece of terrain is at least half the height of the mini (the main exception to this is that the FD cannon gains heavy cover from barricades). This is agreed upon by the players before the game. So if there is a piece of terrain that is 75% the height of an ATRT, then yes, it would gain cover. This would apply before Impact, so could save it a hit. Otherwise, if the opponent rolled enough hits, the cover will be meaningless.

If there is a terrain piece that is well over the height of my speeder bikes, and they are just poking out from the corner of it, do they receive cover? Is that also something that needs to be agreed upon before the game starts?

If a Terrain piece would grant cover to a unit, and that unit is obstructed (ie some of the unit is not visible), then you draw a straight line from the firing unit's leader to the defending minis. If the straight line passes through the obstructing terrain for at least half the defending minis, then the defending unit would gain the benefit of cover. So, somewhat using your example, let's say 1 speeder bike is out in the open but the second one is barely peaking out. Then half the unit would be in cover, and thus the unit would gain heavy cover. Hope that helps.

The grav tank also gains cover from barricades as per the latest rules reference

Edit for reference from 1.5.1

• A barricade provides emplacement troopers with cover

.• A barricade does not provide creature troopers with cover.

• Typically, barricades do not provide vehicles with cover. »However, barricades can provide cover to vehicles if, when declaring terrain during Set Up, the barricade obscures half or more of that vehicle. For example, barricades can provide heavy cover to both standing and ball-form droidekas minis, the X-34 Landspeeder, and the TX-225 GAVw Occupier

Grav tank?

People always miss the ‘GAVw’ designation on the Occupier.

How do they "miss it," and what ramifications does that have? I'm struggling to figure out what you mean.

People seem to assume the occupier is a repulsor grav tank but it’s actually a tracked vehicle. Repulsors don’t grant cover if they obscure a target, whilst tracked vehicles do.

Grave is easier to type than getting past auto correct

Remember too that, within reason, cover can be whatever you both decide on. For example if you want to put down circles of green felt with model trees on them, and declare them forests which grants cover to anything regardless of height of the actual model trees, that is an option. Or if you decide really tall models need more cover than your collection addresses, you can agree that the biggest building you have blocks all LOS, no matter what.

A lot of people likewise come up with simple abstractions for hills, because of all scenery, hills tend to be the least immersion breaking when moved from different background universes and mini scales.

A way you can tell if you would get cover as well is the difficulty of the vehicle moving over it. If you get cover from it, it is difficult movement, but no cover means you can walk or roll right over.

That's not necessarily true. There are no rules that tie cover type and difficulty type together. The terrain works exactly as the players define it pre-game. Players might agree to treat some terrain this way, but it's not a rule.

rule of thumb, more or less.

I dunno. I've actually never seen it played that way. Not to say anyone is wrong to play it that way, it can just be misleading to say it generally works this way.

Thanks for the great responses!
