In spite of the Samurai training, Algren's biggest strength in a fight is still that he doesn't seem to know when to stay down, and he will be bleeding quite profusely before he calls it quits.

Beyond that, however, he's learned a good deal of focus, and is quite skilled in a fight, especially now that his injuries have healed. Between his military experience and his martial arts skills, he's a formidable opponent when facing off against other normal humans.
