Ok, since this is from Ammo, this is probably the most relevant passage:
“The American battles of the Northern Shoulder are considered the most decisive of the entire campaign. Despite being outnumbered five to one, they were able to inflict a casualty ratio of 18 to 1 (in no small part thanks to the 30-06 powered M1 Garand battle rifle) in a battle where 20 percent of their effective force was taken out of the fight.”
A BIG WOWSER ON THE M1!! You always hear how the German weapons were superior.
The US had a superior artillery network they could call upon. Plus they had just fielded radio proximity fused mortar rounds that were deadly to dismounted infantry or panzer grenadiers riding in open top trucks and half-tracks.
Artillery, King of Battles.
The most important part of any rifle is the man firing it.
