In Call of Duty: Modern Warfare 2, prone is a position that allows players to lie flat on the ground, facing downwards, while still being able to hold their gun and aim down the sight. This position maximizes the mass and surface area behind the firing shoulder, allowing players to use their weapons with better accuracy and control, especially when using long-range rifles or snipers. Going prone is achieved by pressing and holding the crouch button, which is the "O" button on PlayStation and "B" on Xbox controllers. While in the prone position, players are vulnerable to enemy fire from behind, so it is recommended to reposition after killing an enemy to avoid being tracked. Crouching and going prone are important stances in Warzone 2 or any battle royale game, as they increase a players chances of sneaking past an enemy or ambushing them.
