Need help with certain Lore/Trophies (friend request)

I usually play every other day, but I only have one friend who plays. Needless to say, I will never get the “When you roll up in a squad like” trophy and getting Lore challenges like Benedict’s that require 3 additional Peacekeepers is nuts.

I primarily play PvE stuff, so any help with Hardcore/Advance is nice. I think I just need Saboteur and Sentinel for Advanced and Sentinel, Experiement, Saboteur and Heliophage for Hardcore. Just send me a friend request, lemme know you saw this here and invite me whenever you see me playing the game.
