My old insurance agent was a Marine and was in the march from the Chosen to UN lines. He said it didn't matter what rifle one had they all froze up from the cold. They had to pee on them to keep them firing and then just fired them as much as possible to heat them up and to evaporate any moisture still on the weapon. The Garandhad more range then the carbines but the carbines worked just as well as the Garand's. He never had or saw a problem with the carbines not stopping the enemy.
