i have customized a bunch of graphics in my mod folder. but now how do i make an executable that makes it go.

It's a command line you must run with soldat.exe
I suggest you create a shortcut and add the paremeter in as follows:
Target: C:\Soldat\Soldat.exe -mod "<folder name in mod folder>"
Be sure to replace it with your own soldat directory, of course if you don't use the default.

Once that's done, all you need to do is run the shortcut to use that mod.
