I added english voiceovers to the standard training missions that ED provides for the L-39, in addition to the russian voices that it has by default. Even tough these voices are computer generated, they are very clear and understandable, and much better than my own broken english.
Inspired by the work of @Highwayman-Ed, who did the same for the first training mission but couldn't find the time to do the rest. I took the liberty to keep his nice mission pic, as the default mission illustration.
The zip file already has the proper file structure, just uncompress on the folder where you have installed DCS, usually it's at C:\Program Files\Eagle Dynamics\DCS World\
