G.I. Joe: A Real American Hero - Season 2 - Eps 23: The Most Dangerous Thing in the World
Cobra takes advantage of General Hawk going to a NATO meeting in Europe and infiltrates the Department Of Defense's computers and promotes Lifeline, Dial Tone and Shipwreck (who's not even in the army) all to the rank of Colonel. The three can't cooperate and are not quite officer material which creates utter pandemonium at G.I. Joe Headquarters. Cobra capitalizes on the situation and attacks a research lab near the Joes' base. The Joes are defeated easily and fall back to Joe HQ. Hawk arrives in the nick of time and organizes a counter offensive, pushing Cobra back.

Synopsis
G.I. Joe: A Real American Hero is a half-hour American animated television series based on the successful toyline from Hasbro and the comic book series from Marvel Comics. The cartoon had its beginnings with two five-part mini-series in 1983 and 1984, then became a regular series that ran in syndication from 1985 to 1986. Ron Friedman created the G.I. Joe animated series for television, and wrote all four miniseries. The fourth mini-series was intended to be a feature film, but due to production difficulties was released as a television mini-series.
