Colonel Hogan, I think, would have a massive amount of Persuasion. Coupled with Klink's Psych Complication: Extremely Gullible, that's how Hogan was able to facilitate the vast majority of his schemes.
I think all the Heroes had the Charm Skill to an extent, coupled with the Complication: Skirt Chaser. For LeBeau it was a matter of national honor to "chase skirts"--Frenchmen being the kings of love and romance. Of course, Colonel Hogan was the most successful at it, he was, after all, the star of the show.
As I remember, Carter was the demolitions expert, Kinchloe was communications, Newkirk was the safecracker and card shark, LeBeau was the chef (useful when bribing Germans with food, especially Schultz) and Hogan was the mastermind, whose brilliant schemes always worked. (They might have gotten complicated, but as the English say, it all got sorted in the end.)
Hope this helps.
