Impossible Challenges

I'm only 24hrs into the game and I've already hit a wall with some of these challenges. Getting 30 objective kills in both Conquest and Escalation is just absurd. Best part it is it pails in comparison to "Get Headshot kills over 200m with sniper rifles". On what map, seriously there's only like two maps in the game that even support 200m snipping. Oh, and don't forget inflicting 10,000 points of damage from hipfiring an LMG. I know Dice and EA want us the play the game for a long while, but what the hell man, this is bogus. I much more likely to drop the game than just go through some challenges that are  unnecessarily difficult. If any one has any idea how to beat these challenges please post bellow, if not for my sake, than for someone else who happens upon this post.
