A squad wipe is when someone eliminates the last enemy player within a squad. For this to count everyone in the squad has to be down on the floor or already eliminated.
Best way of doing this to get a group of 8 players with 4 people in each lobby. The two teams will then search at the same time for the Fireteam: Dirty Bomb game type. Whilst searching be sure to update the other team if you've found a game or not. Took us a few tries to get in the same game.
Once in the same game, for the snow map go to the top right corner of the map. For the forest map we went to the river on the East side of the map. You can check your map by pressing the
to switch to the map tab.
Let one person get all the 10 squad wipes and move onto the next player to avoid confusion. We got it done for 3-4 people. Will continue later this evening.
Definitely a lot easier than boosting the Blackout characters.
