John M. Jackson (Admiral AJ Chegwidden)
"An Admiral acts any damn way he wants to!" is the response most received by Jackson when he spoke to retired Navy personnel for research for his role as Harm and Mac's CO. With roles as navy characters in "A Few Good Men" and "Family of Spies" as well as his role on "JAG", Jackson seems to have the attitude down cold. The married LA man who coaches pony baseball in his spare time has had roles in films like "Glimmer Man," "The Spitfire Grill," "A Perfect World," "The Legend of Billie Jean," "The Hitcher," and "Local Hero." He has guest-starred on many television series including "Northern Exposure," "Sisters," "Party of Five," "Dark Skies: The Awakening," and manages a recurring role on "Wiseguy." His credits for television movies include "Memory of Evil," "The Deception," "Roswell," "Black Widow Murders," "Shattered Vows," "Switched at Birth," "Adam," "Go Towards the Light," "Blind Justice," and "Sudie and Simpson." Also a stage performer, he has had roles in "Pot Mom," "The Deal," "A Voice in the Theater," "Ginger Ale Afternoon," "The Figure and Other Short Works," "The Carney Rod and Gun Club," "Ringers," "Four Corners," and "Are You Now or Have You Ever Been?"
