NOTE: Each trophy requires 3 medals (5 killstreak, 8 kills in 1 match, and 100 kill overall) and for each trophy I will give tips on how to acquire each medal. Remember, all SPECACT weapons are orange when you choose them rather than white.
Here's a tip from our good friend LAWLZilla:
Also a note to anyone working on these and haven't downloaded the DLC yet. You can obtain these weapons through picking it up from other fallen players/squad mates. BUT you can't unlock any of the pins/trophies doing that. But you can obtain kills, and points using the weapons!!
