Potter ( Harry Morgan), and Father Mulcahy ( William Christopher), but still, few would match up to Radar. There were many other heavy hitters, like Maxwell Q. You can't forget Henry Blake ( McLean Stevenson), whose departure in ' Abyssinia, Henry' rocked fans from all around the globe. Then there's the neurotic Frank Burns ( Larry Linville), who is such a hilarious geek that you can't help but love him. Trapper John McIntyre ( Wayne Rogers) would only be a part of the first three seasons, but Rogers' chemistry with Alda and the rest of the cast was so great that his memory left a hole in the series' after his departure. Then there's Margaret 'Hot Lips' Houlihan ( Loretta Swit), who appeared in a majority of the episodes and came out of it easily the most prominent female character in the whole ensemble, as well as one of the funniest cast members.
Of course, you have Benjamin 'Hawkeye' Pierce ( Alan Alda), who would act as the series' comic-yet-wise lead and stick with it until the series finale. One of the main things that keeps people coming back to M*A*S*H to this day is its massive cast of fantastic iconic characters.
