I somehow see the stuff in Chinese! Oo is it meant to?

Your lang is not among the listed in the script so
it defaults to something weird.

Go in to "Handling Greasemonkey script under the Firefox Toolbutton
Click on Edit and scroll down a bit and pick a lang you can read and
put:
case "se": above the line "case "no" (an example how I did it)
since swedish isn`t available but norwegian is.
Save and exit editor and reload a "Send troops" .. done

You might be asked to pick your editor, click your way to
c:/WINDOWS/system32/notepad.exe

yay fixed!
When you release another version can u put case "uk": above case "us":
-Reload
