An Idea I had

I had this idea a while ago. This is how I construct a story.

Here is my character: I figured I'd take this macho marine who happened to like playing such parts as King Arther in small town theaters wherever he was stationed, he was also was a fair farrier and filled his free time with one or another of his private passions.

You are all aware of how close a Recon team can be, so I figured his team mates would be close secondary characters, but these guys have yet to be created.

Then, I thought I'd have my guy suddenly disappear. Of course his pals would go through all sorts of things in order to try to find him (there's a serious lack of information to fill this out though)

In the mean time, my guy would wake up in what seemed like the fifteenth century, lock stock and barrel. He'd be dressed properly (like a land-owner knight) and his castle would be fully staffed with whomever (not sure yet). Heck, I might even give him a league lord and all the rest of the trimmings.

Of course he'd be going nuts trying to figure out where he really is and how to get back, and in the mean time he'd be saddled with responsibilities and decisions to make, and of course the people are going to think their lord is going crazy.

Now I figure all these extras would be actors sworn to secrecy, or maybe people who just like to live that kind of life (haven't really decided yet).

Anyway, aught to be fun, but as you can see, this one needs a lot of research. I'm familiar with military (Army) but not with Marines per se and I'm sure there is some terminology differences to say the least.

Any suggestions would be most welcome
