These are the two 2 Mi-35 supplied by Russia in 2007.
The Mil Mi-24 (NATO reporting name 'Hind') is a large helicopter gunship (and attack helicopter) and low-capacity troop transport (Carries 8) produced by Mil Moscow Helicopter Plant and operated from 1972 by the Soviet Air Force, its successors, and over thirty other nations. In October 2007, the Russian Air Force announced it would replace its 250 Mi-24 helicopter gunships with 300 more modern Mi-28s and possibly Ka-50s by 2015.
In NATO circles the export versions, Mi-25 and Mi-35, are simply denoted with a letter suffix as "Hind D" and "Hind E" respectively.
