Hmm, not sure if it's by the rules or not (don't have my rulebook with me atm) but I believe both horizontal and vertical movement is counted as they still have to expend fuel/energy to make it up and over or on top of said objects. Same for shooting I believe. You do measure the angles as the angle is going to be the longest distance to hit the target. Just using the horizontal would be considered chopping off quite a bit of distance needed to get the shot. As I said, I believe that's how it's suppose to be played and with the true line of sight, it makes sense that you measure the angled shot when shooting because why would you sight downward and at an angle and then measure distance straight across and way above whatever you're shooting at? Same sort of rules for moving skimmers or anything for that matter. If the terrain has a significant vertical element to it (usually 1" or more) then you can't just ignore the vertical part of the movement no matter what is trying to traverse it (unless it's something like the nightbringer or wraiths which have the phasing ability and just ignor terrain altogether).The major advantage of skimmers and jump packs is that they can move across difficult terrain without any impedment. If they start or end their movement on difficult terrain than they have to take a dangerous terrain test (I know that's the case for jump troops and I'm pretty sure it's the same with skimmers).
"There is a cancer eating at the Imperium. With each decade it advances deeper, leaving drained, dead worlds in its wake. This horror, this abomination, has though and purpose which functions on an unimaginable, galactic scale and all we can do is try to stop the swarms of bio-engineered monsters it unleashes upon us by instinct. We have given the horror a name to salve our fears; we call it the Tyranid race, but if it is aware of us at all, it must know us only as Prey."
