Weak Vehicles or Strong Grenades?

First and foremost I thought the footage from E3 today was amazing and it’s got me thirsting for more. However, I couldn’t help but notice in this part of the Multiplayer/Spartan Ops video the player was able to take down a manned warthog very easily. It has me wondering if either the vehicles are substantially weak or the grenades are still a bit too powerful.

It’s apparent that the warthog had already taken damage and there were multiple players attacking it since the main player got an assist for the kill. It’s entirely possible that this was simply a weakened hog. It’s also entirely possible that this is just footage from an earlier build of the game, assuming not everything in the footage here is final. It just caught my eye that it seemed to have been destroyed so easily in the video.

I assumed it was damaged. I wouldn’t mind being able to flip vehicles (especially the ghost) with grenades. If you can do that, then i think vehicles should have a lot of health, if not, i don’t mind them being able to go down easier.

Well in the video it looks like the hog gets hit be a second grenade
