"...if it's an unfair fight you're after, I suppose we could work on disarming drills?" which seems appropriate enough if the read he has on this man is correct. A soldier, but not one he's overly familiar with.

Considering all the soldiers he knows well from back home are variations on the same man, it's strange and somewhat gratifying to know the posture is somewhat familiar- even if it's a bit more casual to the point of informality, here.
