I completed this mission after the Publish 6/ Themepark reset with Covert Rebel Status.

Quest Details: "Mon Mothma needs you to eliminate the strike team that is preparing to attack the Rebel base"

This is a destroy mission.  There were 3 Stormtroopers. One leader named "Strike Team Leader" 7900 HAM, and 2 other Troopers 7300 & 7600 HAM. Only the Leader needs to be killed for mission completion.

Waypoint generated 982m from mission start. Objective was at assigned wp the first time I attempted the mission.

I recieved a reward of 1350 credits for mission completion.

You find 2 storm troopers, and the leader. They all read about 8K HP. Don't worry about the other two, just concentrate on the leader. Bleed him, then attack and fade attack and fade.                                                   

Upon completion of this quest I received 340 credits as my reward... no faction points or loot.                                                                

You talk with rebels on an abandoned rebel base, so you must be rebel...                                                                

Pls if possible insert advice :REBEL ONLY or IMPERIAL ONLY in the quest , thx,..
