Alright I challenge you to a duel kar 98 vs. m16a4. In Stalingrad at 100 to 200 meters no cover, run and gun. Unless you hit with your first shoot you’re going to die. At least on the tactical level small arms are a factor. Strategically less so but if your losing all the tactical encounters. Consistently it can’t be helpful. CM seems like it should be mostly tactical level. In the end assaulting dug infantry is going to be hurt no matter the weapon.
