If we were to say to you "Hey, did we see your super-soldier steal some black oil from Mr. X the other day?", would you know what in the name of weird ties we were talking about? Well, maybe you should brush up on your X-FIles lingo. In which case, io9 has compiled a list of just the sites for you. They are...
The X-Files Conspiracy Timeline
The X-Files Mythology Guide
Cracking the Conspiracy: Making Sense of the X-Files Mythology Arc
The X-Files Wiki
Red Wolf's X-Files Episode Guide
BTW, we know that Mr. X and the super-soldiers were plot threads from two different time periods on the show and they didn't necessarily ever cross, so please, no angry letters. Nerd.
