What is the best way to do the trophy tactical specialist?

[jelover123]

I only have one trophy left for the multiplayer portion of the game; it’s for earning 5 medals  based on a specialist ability in a single game; 

I tried the overcharge ability but I’ve had no luck; any other suggestions since it looks like Team Deathmatch is the only popular mode

Use Outrider's Vision Pulse ability, you will get the Tag and Bag medal for 1 kill of a pulsed enemy. As the pulse has pretty good range and enemies remain pulsed for a few seconds, its alot easier than the other specialists.
