Gunner or driver?

Driver.

one or the other because if the driver is crap I drive but what if hes a rubbish gunner too? so its whatever is most effective, mainly driving.

Always gunner

Driver, gunner always gets sniped

I'm gunnerHEAVYWEAPONSMAN, I'm the guy who crashes the apache into the flag because I cant fly it.

I'll take whatever role is left. If given the choice, however, I would choose "gunner" as driving is not something I"m good at (well, I suck as "gunning" as well, but not as bad).

If I know someone competent is driving, I'll take gunner. I'm a horrible driver, but if it's some F2P or bad-community game and I know nobody, I'm taking driver just so nboody else runs over our entire team.

I depends who I am playing with. If it is a bunch of random people, I always gun because they usually suck. But if I'm playing with friends, driver.

Driver. Insert random awesome Drive quote here

Depends on what game. The only game I can think of that I've played that has vehicles with guns is Halo and I don't really have an overall preference tbh. My decision depends on the map.

I actually prefer to drive alone rather than with someone else because then I can ghost ride and get on the gun while it's still moving and get all the kills myself.
