Ok... so:
:There are many konds of script from movies (intro) to arty nad others scripts.
:There are some radio chatters for example.
:In all of this campaigns and missions (only in "Wietnam 1968-1969 no") are custom voices.
Music is added to all of this mission and campaigns, addons list are in readme.
But all missions and campaign about Vietnam need SebNam2.
Sorry for my bad english but this isn't my native language.
