First and foremost, you NEED to not have entered the simulation. This requires a bit of setup before you even enter it.
To start, you need to kill one of the outcasts (preferably one of the unnamed ones). If you don't want everyone to attack you, then use the Mesmetron and hope that it causes one of them to go berserk. You can then kill them with no consquence whatsoever.
Next, activate the simulation pod to open it. DO NOT get into the pod. Using the grab button, move the corpse up onto the chair. You want it positioned so that, when you sit down, you will be looking right at the body and can access it as a container while looking at it. This may take a few tries to get right; sitting on top of it won't cause it to move, but the pod closing as the simulation starts may shift it around. So move the body, save, and then sit in the pod to see the results. If it moves too far away, then you need to reload until you get it positioned right. Please note that once you get in the simulation pod, you go into "cutscene mode", so your cursor will disappear and you won't be able to tell if it could be selected from your current viewpoint. If it's right in front of where the cursor should be, then it likely will be fine.
From there, play through the Operation: Anchorage simulation like normal. Collect as many items that you want to bring into the real world as you can. Many of the items are unique, retextured versions of old weapons, with VERY high health (so that they won't break for a very, very, long time). If you want a second suit of the winterized combat armor, kill the quartermaster after you've obtained your weapons from him (you can also obtain a second set of weapons by selecting a different weapon form, dropping all of your current weapons, and then talking to him to "trade"). Unlike the other bodies, he does not disappear once killed (although Sergeant Montgomery may attack you if he sees it - happened to me once). I don't know if it is possible to loot Chinese Uniforms (maybe by reverse pick-pocketing an enemy unawares, but the only thing to do that with is the Combat Armor, which was the whole point of coming up with this glitch).
Once you get to the end of the simulation, you will see a load screen before you reenter the real world. As it turns out, the inventory you have in the simulation is NOT removed until after you are back in the real world, and a few seconds AFTER you regain control of your character's functions. As soon as the black loading screen appears, start tapping A rapidly. Once the map loads and your vision goes white, if you push it fast enough, you will select the Brotherhood Outcast's corpse you left earlier, and activate it. From there, dump EVERYTHING from your inventory into the Outcast's corpse. Once you've done so, exit the inventory. The game will then remove whatever's left (if anything), and add your previous inventory back to your character. Once you exit the chair, loot the body of all of the items you just stored on it.
Congratulations; you now have several nigh indestructible toys to waltz around the Capital Wasteland with.
