In Call of Duty games, a good Kill/Death (K/D) ratio is typically considered to be around 1.0 or higher. This means that a player has at least as many kills as deaths during a match or over a longer period of gameplay.
It depends on the game, but generally a KD greater than 1 means you're winning most of your fights, with anything between 1.2-1.6 being really good.
