Edward Winter makes his first series appearance as Col. Sam Flagg, the CIA's most paranoid operative (if such a thing is possible). On this occasion, Flagg isn't the only spy snooping around the 4077th; another agent is likewise trying to ferret out subversives. As Hawkeye (Alan Alda) sends the two agents on a wild goose chase with dumb-dumb Frank Burns (Larry Linville) as the goose, Trapper (Wayne Rogers) has a not uneventful reunion with an old friend. "A Smattering of Intelligence" originally aired March 2, 1974, as the closing episode of M*A*S*H's second season.
