1: krieg's uniform is actually pretty stupid looking if it's not on a whole army.
2: the helmet thing was fatshark actually understanding the sculptor's intention, and not just copying the limitations of the mold, this made many people mad
3: the game engine's floppy physics have never worked and will never work. this will always make anything with hanging bits look bad somehow.
4: the rebreather pack on the chest has two choices. 1: clip into literally everything the player's holding. 2: look stupid as hell. there's no middle ground.
5: people wearing krieger outfits should look stupid, that's lore-accurate.
