S1·E2 The King of the Air Force

Guile and Ryu fight each other, though it is obvious Guile has the upper hand. The sergeant easily overpowers Ryu, and then leaves the bar with his men, telling Ryu that he has guts. Ken takes Ryu home, then fights Guile at the Air Force Base in San Francisco, badly losing as well. This double defeat motivates the two boys to travel to Hong Kong in hopes of improving their fighting skills.
