cant you speak Russian instead ? Palkovnik Pjotr?
Naši bezstrašni (or correct equivalent of fearless) saldaty prigatovleny k baju s fašistami :-) in a strong, confident, however not commanding voice, as it is the player who is the chief :-)
When using GoW, say something like... Artileristy, Stalin dal prikaz :-) (in a commanding voice ofc) (you should know that march) would be helluva fun.
