What is tac stance in mw3?

In Call of Duty: Modern Warfare 3 (MW3), the "tac stance" isn't a formally named stance like in some other shooters. However, it's generally understood to refer to the leaning mechanic.

Players could lean left or right while aiming, providing a small amount of cover from enemy fire while still allowing for accurate shots. It was a tactical advantage for peeking around corners or using cover more effectively. It wasn't a completely separate stance that dramatically altered movement; instead, it was a subtle modification to your aiming position. The exact visual representation varied depending on the weapon and in-game animations.
