In terms of battle tactics, Danny was smart enough to realize he isn't beating Whirlwind in a fight, tracked him down ninja style, and beat him up in his hotel room with his armor off.

You should read John Ostranders run on Heroes for Hire, I think you'd get a chuckle out of Danny's career as a "leader". Captain America, he was not.)
