Additional info on the Commander, courtesy of an reliable Forum Member where we together are Member's on.
"That "Colonel" is polish guy by name and by how he speaks "russian". He is a foreigner, polish merc. That is not even Ukrainian which borrows roughly 50/50 russian and polish language. He said several phrases that are not in ukrainian and not with "ukrainian" accent which is just the Russian way to pronounce certain words and phrases.
Especially at the End where he said "No, no discussion" he says it not in Ukrainian but in polish "Ne, ne ma obsuzhadnie". The "Ne, ne ma" is polish with a polish accent however he tried to speak russian by using the word "obsuzhdanie" which means discussion.
He is a polish mobster of polish mafia and was involved of several mysterious "suicides" of unwanted people."
