There are a lot of folks pushing up dasies all over the world who have been killed by soldiers using
M1
Carbines. I know two men who used the M1 carbine in combat and found its power and accuracy to leave something to be desired. I met another who swore by it. Both men who found the carbine disappointing were using it outside its intended role and after their unfortunate experiences chose another weapon.
I read Murphy's book but it has been many years ago. I only recall one incident of him killing a sniper, that was a
German
who got off the first shot and wounded Murphy in the hip. I could obviously be mistaken about that being the only incident though. Surviving with a wound after having been targeted by a designated sniper is very, very rare. I believe that sniper's rifle was the one that was in the Life magazine story.
Anyone who does what Audie Murphy did in his military career has to be very brave, very skilled, have a very cool head, and last but far from least very lucky.
