The MVP achievements can easily be done on Squad Rush with a friend. Both of you be on the attacking side. When the match starts, you go for the MCOM stations and have your friend cover you. You get 600 points for each MCOM and there are only 2 in Squad Rush. You can get first place pretty easy this way.
For 2nd and 3rd place, have your friend arm the MCOM stations and you cover them. Make sure you cover the MCOM and rack up kills when the other team tries to disarm it.
This is one of several ways to get this achievement. Most of the time, just playing the game and not camping will be enough. I have got MVP several times without trying and had a horrible K/D. If you forget about K/D you will be fine.
