Krauser tags Leon before there's even time to react. Not to compare Leon Kennedy to Geralt, but people are making this out to be more of a stomp than it would be. Krauser is infected by a master Plaga strain, meaning he has enhanced strength, agility, the ability to mutate his arm into a large bladed weapon that can also block projectiles. Not that he necessarily needs it, as he can bullet time.
Not even taking into consideration that Krauser has explosive arrows, military-grade drones. Honestly, Geralt using signs is probably what gives him the edge here.
