Translation of missions and campaigns in Russian. (text)? (Arma 3)

I see a lot of interesting campaigns, but they are all in English.
Here is from a file with the campaign (.pbo file) to get the WHOLE text, and for example in the translator translate it and paste the Russian words are there?
PS:In creating missions in the editor ARMA I do not understand
-----------------------------
Well type some text editor for example to open the file, or some prog, (just do not understand how all these campaigns are doing). and type all the text to copy from there, for example to translate and Yandex translator and put Russian text....

Or it will not work?
