Mutsuga Yamazaki

Overview:
The serious and hard-nosed leader of the Cougar Squad. He continually tells his squadmates about their shortcomings to keep them improving, and cares about the safety of them. Yamazaki is killed when he shields Ukumori's plane from gunfire; ironically, Ukumori continues to insult Yamazaki throughout the game even though his sacrifice saved his life. After Yamazaki is killed in action, Lynx is promoted to captain and renamed Cheetah, thus renaming the squad the Cheetah Squad.

Trivia
the relationship between Lynx and Yamasaki seems to parallel that of Manfred von Richtofen and Oswald Boelke, respectively. Both are special bonds between a master and his student, and both end tragically with the death of the master.
