What the carbine was designed for, and what the army may have actually used it for, are not necessarily the same. The intended purpose of the carbine was to be a replacement for a handgun.
Very true. It was designed to replace or supplment the handgun on the theory that a small rifle would be much easier to shoot than a handgun for troops that didn't need the standard service rifle.
The only problem I have with the oversimplification is there seems to be this widespread belief that since the carbine was *intended* for "non combative" personal, it was actually only issued to those kinds of troops. What the army planned to do with the carbine and how the carbine was actually issued in WWII were two different things. In reality, all sorts of "front line" troops were issued the carbine. They didn't all just get a carbine from some cook or truck driver in a trade.

I doubt if Audie Murphy carried one in the field as a first line of defense weapon.
Actually, Audi Murphy said in his autobiography that he prefered the carbine. He was armed with a carbine during the action where he was awarded the Medal of Honor. (Granted, he also used a vehicle mounted .50 M2HB in that fight).
As to the effectiveness of the M-1 Carbine, and what the soldiers thought of it, that's a different issue. From what I've read, troops in combat either loved the carbine or hated it. There was no middle ground. Some found it light, handy, and a good weapon. Other soldiers didn't think it had the "stopping power" of the Garand on a human target or didn't like the lack of barrier penetration when compared to the .30 - '06 round.
The Marines liked the carbine in the Pacific during WWII, but pretty much took the carbine out of service after it reportedly failed in the harsh winter conditions in the Korean War.
John George was a pre-war High Power competitor who served as an officer in "Merrills Marauders" in WII. In his book, "Shots Fired in Anger, " he wrote:
"The M1 carbine turned out to be the ace weapon of the war, as far as I am concerned. It was light and handy, powerful, and reasonably accurate ... The cartridge was powerful enough to penetrate several thicknesses of helmet, and to perforate the plates of the Japanese bulletproof vest, which would only be dented by .45 auto slugs. It was flat shooting enough to have practical accuracy at more than 200 yards ... For many types of offensive fighting, such as sneak raids and infiltration tactics, it was often superior even to the M1 (Garand), penetration being the only point of difference."

In "modern" usage, Jim Cirralo reported that the NYPD "stakeout squad" had great success with the carbine loaded with "soft point" loads in the 1970's.
