Realism functions identically to the Veteran difficulty, carrying the same damage and weapon mechanics. The only difference, however, is the limited HUD display. Gun display, grenade slots, ammunition value, and friendly NPC nametags are completely absent in this difficulty. Enemy nametags, however, are still visible. This also includes a choice for players to choose what time of day they would like to play on whether it's day time or a new night time mode. Realism is one of the most competitive game modes that has ever launched in all of the franchise. Team positioning and communication is key if players are focused to win rounds.
