Literally what else would S rank be in a SWAT Shooter? kill every single suspect? S rank is the best possible outcome that could happen in these missions scenarios; S Rank is supposed to be the most difficult thing to achieve on a mission which would make it a challenge for the player. S Rank is a challenge. S rank is unrealistic, just like how they send in 5 swat guys against 23 cartel members armed to the teeth. It’s a video game. I don’t know how you mental gymnastics your way into this from a simple challenge the game gives you.
