Players have a measly 100 hit points, so if you think they are "bullet sponges" that require "a full magazine to drop one guy" then, frankly, you simply do not know how to fire your weapon accurately.
Hardcore players are not being silent, as your own post indicates. Since Battlefield 6 opened, we have been reading over and over again about these oh-so-special players that require their hardcore servers. But the truth is there are FEW players who really, honestly, passionately desire a hardcore server.
I honestly hope that EA DICE will give you an official hardcore server so people will finally stop posting weekly messages demanding an official hardcore server.
And, by the way, we are mostly Americans here and Americans are very familiar with firearms... more so than most other countries.
I was in the U.S. Navy for 20 years and have experience firing mounted 50 caliber machine guns, as well as shotguns which are used for something we call "Repel Boarders." I also received a pistol expert ribbon for the 45 caliber handgun. I am very familiar with all manner of pistols, shotguns and rifles.
Have you done anything similar? Probably not. So, enough with the posturing about how you need a hardcore server to satisfy your bloodlust.
One other note, the Battlefield series is not a military simulation. It's a just a first person shooter video game.
