The players will face off against a group called The Bodark. It's not clear whether these elite soldiers are literal werewolves or not, but UbiSoft takes them from Russian legend of Bodarks, who are men who willingly become lycanthropes.
According to the video, "The Bodark is a dangerous group of elite and fearless soldiers. Equipped with state of the art weaponry, they are a high threat even for highly trained Ghosts."
If this is the case, maybe the Ghost Recon team should get some silver ammo.
