TL;DR
Use the soflam once you hit level 56
Level it up in solo coop until mastery 12 then move to breakthrough games.
Sit back and scan the areas
Should go from mastery 0 to 40 in about 3-4 hours.


Long Winded Answer
After all of the updates and patches to make the proximity sensor less efficient and smoke grenades are slow, I wanted to share how I got this achievement.

I got this achievement in less than 3 hours playing breakthrough with the soflam. You don’t unlock this until level 56, but I decided to give it a try because the medpen was leveling slowly. In 1 match I hit mastery 5. I went to solo coop to level up to mastery 12 against the bots and then went to normal matches.

I tried to pick area that were far away, usually in my own spawn still, that would overlook an objective and just move the RS from left to right slowly. From what I can tell, you get 1 point for each spot and then you get another point for each assist. I’m not sure if you should be able to spot infantry like this, but I would give this method a try now in case they decide to patch it and let it only spot vehicles.
