The Russian Air Force recently received the first four of several hundred updated Mi-8 helicopters. The decision to buy these was made two years ago and the order was placed in 2013. There are several updated Mi-8 models involved. The ones just delivered are the Mi-8AMTSh. This is described as a "combat assault helicopter" that can be equipped with missiles and autocannon, as well as carry up to 37 troops or four tons of cargo.
