"Get Your Filthy Hands Off" trophy easily get on Warzone because one game mode requires interrogations. During interrogation game mode, try follow your teammate, the opponents tend to do interrogation on your teammate, then you have many chance kill opponent.

"Redeemer" trophy can get on Guerrilla Warfare and Warzone. Same as interrogation, try follow your teammate. As long as your teammate injured by opponent, kill opponent first before rescue teammate. The bleedout time very short, so action must be fast. I'm agree revive teammate chance not high because majority weapons directly kill teammate and not allow bleedout. I only revived 2 teammates during grind 100 online matches. As long as you stick with teammate as much as possible, sure can get a chance revive your teammate during grinding 100 online matches.
