The Gary glitch in Aiding the Outcasts
The Gary glitch is one of the most well known glitches/exploits of the game. This glitch takes place in the Brotherhood Outcasts bunker. The Outcasts will ask you to get into the machine and pass the simulator to get into the vault, that has refused to open, that is full of stuff. I will bullet the different steps involved to do it right.
When you go into the main hall leading to the simulator machine, you turn to your left.
There is a door with a Gary clone on the other side who is dead already. Drag him into the simulator pod.
Set him up so that he is draped over the seat of the pod and can remain still when not being held put.
Go through Operation Ancherage and get as much supplies as you want from inside the simulator.
Complete the quest inside the simulator
Rapidly hit the select key or button until you get an inventory list.
Deposite everything you have onto the Gary clone that you were able to access
Exit the pod and turn around to take your stuff out of Gary's inventory.
This is how you get the Winterized Combat Armor to have in the Capital Wasteland without mods or console commands.
