I just finished reading two books about the Korean War, "Pork Chop Hill, The American Fighting Man in Action", by S.L.A. Marshall, and "The New Breed", by Andrew Geer; in both, the U.S. Army ends up way down the scale when compared to other outfits. In the former, two Ethiopian-performed recon and ambush operations are highly praised by the author, and used to illustrate the clumsiness with which similar patrols were conducted by Army units, taking heavy casualties without much to show for them. In the latter, during the fight for the Pusan Perimeter, Marines have to rush all over the place to plug the holes left in the line by Army units clobbered away, while during the army-sized ambush at the Chosin Reservoir, with the U.S. and British Marines fighting their way out of the trap, refusing to be evacuated by air or even to leave their supplies behind, the Army´s 7th Division takes a thorough beating, with lots of MIA and just a few weaponless survivors coming out only due to the "mercy" of the CCF and the support of Marine Air. X Corps command, made up mainly of Army brass, also takes a lot of heat, with several utterly wrong (and tragic) decisions under its belt. I read several books about the Korean "Police Action" in the past, but never had a chance to appreciate this kind of comparison. Was there really such a big difference in quality? What caused it? Or is it a case of biased writing?
