Da da, the english thingy:
Download

Instructions, for those who aren't familiar with mods:

1. Create a folder called @english inside your Arma2-folder
2. Inside the @english-folder you create two folders: AddOns and Dta
3. Unpack the .7z-file you downloaded somewhere. You get three files that end with .pbo.
4. Move languagecore.pbo to Arma2\@english\Dta\
5. Move language.pbo and languagemissions.pbo to Arma2\@english\AddOns\
6. Add -mod=@english to the end of your Arma2 shortcut's command line. DO NOT RENAME THE EXE. It might look like for example this(nosplash removes the annoying splash screens when starting): D:\Pelit\Arma2\arma2.exe -mod=@english -nosplash
