It Followed Me Home

Travel to the key location on your radar and activate the Stalker Controller. Once the Stalker drops form orbit, quickly lead it into the Bane Refueling Station to the north. Once you've led it close to the mission indicator, the Stalker will turn its guns on nearby Bane and you will have completed the mission. Report back to Retread Vincent.
NOTE: This requires you to get a tamed stalker and lead it through the front gate of the Bane base in the south east quadrant of the map. The base is heavily defended, the way is blocked by a fairly strong shield, and the mission is timed so it isn't easy.
