I use GameHacker, so far able to hack the level to level40 and also dog tag. To hack the level in any mission each time you and your brother kill an enemy there is +2XP or +2XP+10XP shown. For example you got +2XP for first kill, so search for 2. Then got +2XP for second kill so search for 4. Repeat till you get only 1 number. Change it. For dogtag in chapter 1 but I can't remember whether Campaign1 or Raid there is a mission where you need to disable AA guns. In this mission you will find dog tags at least 2 times. 10tags each times. So search 10 for the first time then 20 for second. You should be getting a number so change it to whatever number you like. Finish the mission and you'll see the new number. Still figuring out how to get free medal.
