You Can Depend on Me

 is a side quest in Fallout: New Vegas.

Objectives

 * Deliver the Crimson Caravan invoice to Dr. Hildern at Camp McCarran
 * Convince Henry Jamison to quit.
 * Buy out Cassidy Caravans from Rose of Sharon Cassidy.
 * (Optional) Get the Gun Runners' manufacturing specifications.

Walkthrough

 * Speak with Alice McLafferty at the Crimson Caravan to begin the quest.
 * Deliver a parcel to Dr. Hildern. He can be found in Camp McCarran inside the terminal on the ground floor.
 * Buy out Rose of Sharon Cassidy's contract. Speak with her at Mojave Outpost, at the bar. You can complete this objective via a variety of skill checks and will be rewarded with 500 caps and NCR fame regardless of which option you select (barter, speech 50/75). (Once she sells her company she will be available as a companion). Alternatively, you can also kill her with a silent weapon, so long as you aren't detected doing so (you will not be paid if you finish the objective this way, but you will be able to move on to the next quest).
 * You need to convince Jamison to quit his job. He can be found at the Atomic Wrangler Casino at a slot machine by the bar.
 * If you have a high enough reputation with the NCR, you can also convince him to quit and receive 500 caps (no skill check needed)
 * You can convince him to quit his job without any checks and earn 300 caps
 * Passing a barter check (50) here will increase this to 400 caps
 * You can convince him to quit using a speech check (50) and earn 500 caps
 * You can kill him if you have a silenced weapon so long as no one catches you
 * Acquire the Gun Runner's secret manufacturing specifications.
 * Head to the entrance of the Gun Runner's factory, and activate a Stealth boy...alternatively Chinese Stealth Suit and "La Fantoma" magazine. Pick the lock (Average) at the gate (negative karma earned). Make sure you are hidden, and not detected. Head to the front door then all the way to the back of the building. Grab the information off the computer terminal to the right of the room, and head back out again. Make sure you are still crouching or else the guards will see you and attack. (While crouched, if there are weapons on the workbenches, you can take them and the guards will not notice.)
 * Alternatively, There is a shift change sometime between 10pm and 11pm (while the gun smiths are conveniently asleep) during which the player can follow a guard through the locked gate. The guard will leave the door unattended briefly to patrol the compound. By moving quickly and quietly, the building can be entered, the data retrieved, and the compound exited before the guard returns to his post. At this point, the gunsmiths may still be awake. If this happens to you wait until around 6am and they will have gone to sleep. (There are claims that this does not always occur, and the only way to complete the quest is by picking the lock to the gate with a Stealth boy.)
 * Alternatively, You can shoot a guard through the gate and have them chase you to unlock the gate, and then stay away 3 days to cause them to be neutral to you again.
 * Alternatively, when requested, you can deny the Gun Runner's section of this quest altogether. You will still receive the experience, and the objective will be completed. It will also allow you to continue onto the next quest that McLafferty offers you : Pressing Matters.
 * Alternatively, you can just kill everyone, as it will not stop you from trading with the Vendortron. Be careful not to kill Isaac, as he is involved in an unmarked quest.
 * Alternatively, Open the front gate (making sure you are hidden). Once inside, sneak to the left hallway where there will be a guard. Kill him and put on his armor. Now, you can casually walk to the room with the workers, go to the computer to the right, and download the info without getting into any trouble(note this may not always work).
 * Alternatively, pick the lock on the front gate, run in while the guard's back is turned. Enter sneak mode, and hide behind the desk in the lobby. Use the grenade launcher, and fire it at the lefthand corner of the lobby. The workers come out to investigate - you can run in, download the specs, and run back out. However, when speaking to Alice, she will tell you an intruder was detected, and you will not receive the full reward, even though you do not have to kill anyone this way.

Bugs

 * Sometimes Henry Jamison may have no dialogue options, just "bye".
 * If you have completed "There Stands the Grass" quest, Doctor Hildern might glitch and not accept your parcel. In this case, the console command will complete first stage, and allow you to progress.  In the case of the Xbox 360 and PS3 for which this bug also exists, there is no known way to correct the lack of an option to give Dr Hildern the invoice.
 * When you complete this quest and hand in the holotape schematics taken from the gun runners, a lot of items/weapons/apparel will disappear from your inventory. This has happened on the PS3 version with the most current update. A way around this is to give all your items to a companion, however this can fail as well.
 * During the first leg of the quest, Doctor Hildern may never appear, though he does show up on the compass. To force him to spawn in front of you, open the console and type and then.
 * When you walk out of the office after giving the package to Thomas Hildern there will be none of your HUD showing and you can hear a very deep breathing sound. Also, you will not be able to move or access your Pip-Boy.
 * Sometimes the the dialog option to start the quest is missing from Ms. Lafferty, one way around it is by using console command  will allow players to pick it up. (This so far is the only thing that worked).
