I came across this article, in business insider, and their No 1, most deadly helicopter gunship is the Ka-52 “Alligator”. I think the picture below/overleaf is dramatic, and I also think shows one in Red Army (or Air Force) livery.
This picture comes from the business insider article, it is stored and processed for reasons of longevity and performance. i.e. this picture is a cached picture of the version on the BI site.
