I made this list by looking through lists of the guns in Wolfenstein TOB, TNO, and TNC and finding similar weapons and attachments in H3VR. If there's a better weapon or set of attachments for a weapon, please comment it/them.

Instead of splitting the sections into the games themselves, I'm splitting this guide into the wartime weapons and post war weapons. This is mostly because a lot of weapons just repeat or have very slight changes between these games, so having one version of each gun will be vastly more comprehensive and efficient than repeating guns several times.

I'm not adding weapons from any other Wolfenstein games generally because of a lack of familiarity with them. If anyone who reads this guide wants me to add a section with weapons from a certain Wolfenstein game or games, comment with all the info about it.

If you want me to do something similar to this for another game or a war, comment that too.
