Regulator HQ

Regulator HQ is a house in the Capital Wasteland and the headquarters of the Regulators. It is the farm house located north of Wheaton Armory and west of Canterbury Commons. This location is given to you once you add the Lawbringer perk to your character.

Outside of the house are three brahmins, and inside are three Regulators. Sonora Cruz should be outside tending to the cattle, she may also be inside. It is entirely possible that she is no where to be found and you will have to go looking for her.

Glitches
It is unconfirmed whether it's a bug or part of the game, but approximately 4 out of 5 times you fast travel to the Regulator HQ (tested in Xbox 360 version), random enemies spawn that kill the brahmin and then attack you. These attacks may cause Sonora Cruz to run away and disappear if she is outside of the building. (Cruz is important as she is who buys fingers off of you if you have the Lawbringer Perk)
 * Notes:
 * Sonora Cruz may have escaped very far from the HQ if outside when danger was present, usually she will "flee" and run away, beware as there are some threats around the HQ and most notable of which is the Enclave camp south of the HQ (at higher levels).
 * Once all threats are suppressed she will still be "fleeing", talk to her and she will stand once again letting you "shepard" (pushing) her back near the HQ.
 * Her Regulator Duster will not cover her enough from Giant Radscorpion attacks or the Enclave's Laser and Plasma shots. If she wanders off, Reverse Pick-Pocketing better armor is advised.
 * If you can't find her after an attack, be sure to thoroughly search in all directions from the HQ, she has been found to have ran as far off as past the cliffs to the south!
 * Occasionally when you fast travel to the Regulator HQ, added in with the Radscorpions/Yao Guai that spawn, you'll also find a sentry bot. This can be particularly devastating if you've got a weak follower (killed dogmeat on my play), or if any of the regulators start fleeing outside (Since the bot has a missile launcher and a gatling laser). (Happened on PS3 version.)
 * If you enter the Regulator HQ with Fawkes, the Regulators will flee but after about a minute they will stop. They do not turn hostile if you bring Fawkes. (Confirmed on Xbox 360. Also worth nothing that the Regulators inside did not flee at all when I entered with Fawkes.)

Chinese Army Mobile Command HQ
The Chinese Army Mobile Command HQ is what appears to be a communications centre set up in a ruined trailer. It is not marked on the world or local map, the nearest marked location is the Regulator HQ. Looking due east from the Regulator HQ door a truck and trailer is visible high above toward the end of a ruined section of freeway overpass. Head up to the trailer from the base of the freeway (north east from the Regulator HQ) and travel up until coming to the trailer. In the trailer there is a ham radio, a ruined terminal and some useful loot in three metal boxes and a filing cabinet.


 * There are three metal boxes and a filing cabinet with random loot.
 * On the table with the HAM radio is a Chinese Army: Special Ops Training Manual; perhaps the only clue to the trailer's original purpose.
