Regulator HQ

 is a farmhouse that serves as the headquarters of the Regulators. It is located north of the Wheaton Armory and west of Canterbury Commons.

The coordinates for this location are only given to you once you take the Lawbringer perk. It is impossible to get inside without the Lawbringer perk as the door will be locked and will require a key. Also, the Regulator HQ marker will not appear on your map.

Inside the Regulator HQ, three Regulators can be found along with Sonora Cruz. Outside stand three Brahmin which can sometimes be seen being tended to by Sonora.

Glitch
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 (PS3/360), random enemies will spawn that will attack the surrounding Brahmin and possibly the Regulators. These attacks are commonly conducted by Giant Radscorpions, Yao Guai, and Deathclaws (at higher levels).

These attacks may, and most likely will, provoke Sonora Cruz into fleeing and running away. This can happen with her either inside or outside the Regulator HQ. This seriously works against you as Sonora Cruz is the only individual you can turn Fingers to for caps.

Sometimes if you enter the Regulator HQ a Deathclaw will randomly spawn in the building and attack the player and the regulators. This will cause Sonara Cruz to flee. (Xbox 360 confirmed)


 *  Tips 
 * Do not enter the HQ while you are in combat as this will cause all the Regulators to flee, making Sonora Cruz almost impossible to find.
 * Be aware that if Sonora Cruz does flee, this leaves her open to surrounding enemies, most notably, the Enclave encampment not far from the Regulator HQ.
 * Her Regulator Duster will not protect her from Giant Radscorpions or Enclave Soldiers. If she wanders off, reverse pick-pocketing better armor onto her is advised.
 * Once all threats are suppressed she may still be "fleeing", but talking to her will stand her up again allowing you to push her all the way back to the HQ, should you decide to take the time to do so.
 * If you can't find her, 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 HQ, added in with the Radscorpions/Yao Guai that spawn, you may also find a Sentry Bot which can easily take down all the Regulators with its Missile Launcher arm and Gatling Laser. Be advised!
 * Even if Sonora Cruz flees from the HQ, if you are lucky enough to find her, she will still accept Fingers and give you your caps.

Bugs

 * When my character jumped from Bad to Good, the regulators still had my characters bounty notice. I had been there a few times, and they did not attack. Then, one time I went in and my followers immediately killed all the Regulators except Sonora.
 * Occasionally after a battle with any wasteland creature, a bug may occur where the player's followers will go berserk and kill all remaining Brahmin or nearby caravan traders despite being neutral to you.

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.
