There is no randomness in locaton or direction when spawning directly to the VH. I ran into a situation where a player was camped in the hanger directly behind the spawn hanger. I litteraly gave away 20 kills testing if there was a viable defense aginst this. No tank could swing the turrent fast enough, and I repeatedly shot the panzer with the osti 37mm with no effect.
For the most part in AH1 campers could be defeated depending on the terrain at the spawn point, and the spread of the spawn locations would give a player a chance, but this situation would be possible at any vehicle field. Even if there happened to be air support, the camper is effectivly invisible from the air.
