Did you ever watch the TV show E-Ring, discontinued in 2006 ?

Major Jim Tisnewski, until recently an active special forces commando, takes up a Pentagon job as assistant of US Army colonel Eli McNulty. He now must learn to battle the Pentagon way against politicians and careerist officers who often oppose what makes operational sense. On occasion, Jim returns to his team or otherwise interacts with his former mates, especially Bobby Wilkerson. Jim also develops a triangle relationship with a CIA agent, his lover, and Pentagon lawyer Samantha 'Sonny' Liston, who has a crush on the hunky officer-gentleman.
