10. Alpha Group, Russia
An arm of the well known and feared Spetsnaz, the alpha group is the fiercest in their group. This well known task force started out in the mid 1970s and came to the limelight during the invasion of Afghanistan. They are known for their brutal vengeance and heartless taking down of the opponent.
Due to their unique operational strategies, the unit is also known as Spetsgruppa “A”. The unit did come under heavy criticism during the 2002 Moscow theatre hostage crisis, when in order to knock out militants, FSB’s Alpha group used chemical gas which led to the killing of 129 hostages as collateral damage.
