Easy enough to do in the Foundation DLC. Simply drain an enemies health down as much as possible yourself, entice him near to your deployed ranger and let them finish it off with their weapon.
Note: The actual correct title for this achievement is "Have a Deployed Ranger kill 5 enemies", not 50. This is why the achievement pops before described.
