You will see in the screenshot that both the GPS is shown and the quest area is clearly marked (the upside down white triangle on the mini map)

I have been working this quest for days at different angles, different levels, Killing the Drill Sergeant first to Not killing him at all, staying close to Lilith and placing the Water Barrels and Not staying close to Lilith and Placing the Barrels all with the same result. My deaths (they were because I also needed the screenshots for this report, and I couldn't find the correct key to do a screenshot in time this morning to prevent them ).
