While I've never tried to destroy a vehicle with armor lock, apparently it can be done so it's worth a try. The achievement that looks to be the most difficult is You Ate All the Chips. Getting all of the flags for the whole round will mean you need to team up with friends and take turns getting the achievement. It would be nearly impossible to do with a random group of teammates.
