I was playing last night after reading this thread, it gave me an idea.
(On that night time snow map)
I went assault as attacker, upon landing i dropped an ammo box and shot the quad down to like 10 health and the covered the quad in c4.
Once i felt it was an ample amount of explosives i drove it up to B (i think, whichever is closest to the water) and drove it up the hill inside the building and rammed into an inner wall.
Big explosion.
I was killed instantly but it netted me a double kill, and took out the building crushing the mcom.
C4 is very fun to play with.
