Reilly's Rangers (quest)

 is a Fallout 3 quest. It is also an Xbox 360 and PC achievement.

Objectives and walkthrough
Reilly's Rangers is a map service group in the wastelands of Fallout 3. There are five members of Reilly's Rangers, they are:
 * Donovan: Reilly's Rangers' engineer
 * Brick: Reilly's heavy weapons woman, uses a Minigun, which at the time is the special weapon Eugene, and therefore will take the 5mm Round found on Theo's person
 * Butcher: The Rangers' medic
 * Theo: The Rangers' Jack of all Trades, who happens to carry most of the Rangers' ammo, and who is killed in action.
 * Reilly: Leader of the Rangers

This Quest can be started in three ways:

Exploring at the National Archives building near the Mall Northeast map marker, you will pick up the Ranger Emergency Frequency from Reilly's Rangers needing assistance.

You meet Reilly in Underworld, the Ghoul City situated in the Museum of History in D.C. (near the Washington Monument). Reilly was wounded by Super mutants on one of her excursions and is lying unconscious in the Underworld hospital. If you manage to wake her up (60 medicine skill) or convince the Doc to wake her up (speech skill), she will ask you to help her team of Rangers, which is trapped on a hotel roof not far away.

You can also enter the Statesman Hotel without having picked up the quest. Once you're in, you cannot get out (unless you have a savegame from before entering the building) so you have to make your way up to the rooftop. There you'll meet Reillys Rangers. The quest starts when you talk to them.

Directions
Reilly's directions to Statesman Hotel: "Using the Metro tunnels, head north from here to Metro Central. Then look for the tunnels to the Dupont Circle Station. Exit from Dupont Circle Station into the Dry Sewers and follow to Our Lady of Hope Hospital." These directions require a little interpretation: after leaving Dupont Circle station, you need to find East Dupont, which is a short overground walk away. At East Dupont there is a flight of steps leading down to a door marked "Hospital Maintenance", which leads into the Dry Sewers.


 * Despite Reilly's directions, an alternate (possibly easier) way to get there is to go to the Vernon Square North Station near Vault-Tec Headquarters. Go into the tunnels and head south to Vernon Square Station. Exit there and you will be in the plaza with the hospital and hotel.


 * You can only reach the rooftop of the hotel by going through the hospital first. However, it would be wise to clear the entrance immediately inside the hotel as this will make the battle as you leave the building with the rangers much easier. After doing this, proceed to the hospital.
 * You may also want to clear the building diagonally across the street from the hotel and hospital as it contains Super Mutant riflemen in the windows.


 * The Fission Battery required to repair the elevator can be found in the room (the Statesman Hotel Restaraunt) just before you go to the roof. It can be found on a destroyed Maintenance Protectron in a supply room.  Follow the quest map indicator. Or you can just bring one. (Note: One can be found on your way through metro station in a back room. This room is located in the long hall, back right corner, before you reach the main platform. It takes an average skill of lock picking to unlock the door.).


 * Reilly's note on the location of Theo's body is a bit misleading. The note says Theo's body is in a stairwell on the 2nd floor of the Statesmen Hotel.  However, this is not techically true as the 2nd floor of the hotel can be accessed through the ground floor entrance and accessed via internal staircases and balconies.  Reilly is actually referring to perhaps the 3rd floor of the hotel, which is the first floor you get to after crossing the crane boom from the hospital.


 * To recap, once you have arrived at Vernon Square, the other authors have suggested you...
 * Clear the 1st/2nd floor of the hotel, and perhaps the surrounding buildings as well, if you want to ease the Rangers' extraction from the hotel.
 * Leave the hotel, enter the hospital, and proceed up to the 2nd or 3rd floor where the crane boom connects it to the 2nd/3rd floor of the hotel.
 * Find the Fission Battery on your way up to the roof of the hotel.
 * Reach the roof of the hotel. The rest should be pretty straight forward from there.

Reward(s)
The quest rewards for this are either a suit of Ranger Body Armor (which can be repaired using any combat armor) and/or Brick's special mini gun: Eugene.

After rescuing Reilly's Rangers and offering Reilly your help for their mapping service once you return to the Ranger Compound, she will give you a Geomapper Module. As long as have the module in your inventory, it will record every new location you discover, for which Reilly will pay you in caps every time you return to the Ranger Compound and talk to her. Don't forget to speak to her right away, after receiving the Module. She will pay you for the locations which you already have on your map.

The Rangers themselves will also offer services, if they lived through the journey back to their headquarters of course.


 * Donovan offers to repair your weapons and apparel; however, he charges caps for the service.
 * Butcher will emulate a normal Doctor as he can heal wounds (For free on top of that), but he cannot cure radiation poisoning or clear any addictions.
