Before Neil Marshall scored big with The Descent he directed Dog Soldiers. This is a criminally under seen flick. It follows a group of British Special forces guys on a training exercise, who are then attacked by werewolves. The film is a down to earth version of Predator, except with multiple werewolves attacking there is a greater tension. If you are not sold yet you won't be. Embedded below is the full movie.
