“When the Marines went on the offensive on Guadalcanal during August of 1942, they carried the M1903 with them, and the Springfield was the primary battle rifle throughout the fighting there. Even as the U.S. Army began to appear in the Solomon Islands campaign, not every G.I. carried the M1 Garand. Many Army units in the PTO were equipped with a mix of M1903 and M1 rifles until the end of 1943, and the M1903 remained in USMC first-line service until the end of WWII.”
To duel the panther, even thought there was a LOT of m4a2 regular Shermies, I’d suggest the m4a2e8 “easy 8” (no I’m not a fan of “fury”, hated the movie but loved the vehicle waaay before.). It’s a bit like a USA Panther, would fit a bit better imo. Unless axis Panthers are very restricted in numbers
Edit: I know e8 ain’t in game (yet), but seeing as they use a lot of WT assets, AND we got the Brit’s “e8” (Firefly), it wouldn’t be too far fetched.
