Two in the same episode.
First, Bud steps on a landmine and is evacuated to a hospital in a desperate attempt to save his life. The attempt fails. He dies on the operating table. And then, somehow, and we should perhaps not examine this too closely, his spirit perceives his son calling for him, and he comes back to life on the table, long enough for the doctors to save him.
And then, At the very end of the episode, the doctor comes out to say that Bud has survived, not revealing the above situation, to Harm and Mac, who've been waiting anxiously for their friend's fate. Mac is relieved, and turns to look at Harm off camera ... then softly says his name. Harmon Rabb, ace aviator and tough attorney, has broken down in silent tears of relief. She silently sits down beside him, resting her head on his shoulder as they rest from the horrid tension of this awful day.
There is one episode in which Harm is surprised to learn that Webb, through his mysterious contacts, has arranged the release of his half-brother Sergei from a Chechyan prison as a Christmas present. Webb tells Harm that a present is coming over the telephone while shells are raining around him in Afghanistan.
