Detailed walkthrough
If you are not wanted by the NCR this one will be close to a simple hack and slash. You should be able to walk into the camp with no issue and begin in a strategic location, try to pick a place where your back is against the wall. There are a lot of NCR men with some MP and the dogs, they are all simple but if you pair them with the mission targets it may get messy, so take them on one at a time.

Quartermaster Mayes is the average joe of all those you have to kill, he walks among the men and there for if you go for him almost everyone will know, but he does not take a massive amount of damage. Also you might be able to catch him sleeping at night, some of the others do not sleep!

Dr. Richards is among the easiest, maybe, because he is in the medical clinic most of the time, alone. If you go for him first you should be able to hit him with a one shot and come out unnoticed. He sleeps in a tent down from the Medical Center.

The only target that you may have difficulty with is Tech Sergeant Reyes, as she has two guards and is in a well opened close quarters tent. Although it might still be a harder task it is still not that difficult. Both her guards, like most of the ones outside of the tent, have caravan shotguns so try to keep some what of a distance. She herself is almost always sitting down and there for is not usually in the fight until a shot or two goes off, but still is the most dangerous of the three if she does manage to get up.

Major Polatli, is the wanderer of the targets he maybe inside with the Tech Sergeant, but he is usually outside by the power station near the communications tent. He is the other target that sleeps.

Alternatively, characters with a decent Sneak skill can sneak attack all but Sergeant Reyes while they are sleeping. If done with a melee weapon while hidden, killing your targets will not cause the entire camp to turn hostile. If, for whatever reason, you are unable to catch one of your targets alone, reverse-pickpocketing C-4 is a good option. At the NCR blockade just up the road from Nelson, there is a footlocker with 2 packs of C-4 and a detonator.

Behind the scenes
