"Left handed gesture. Press (Left on D-Pad on Console or Left arrow on PC) to use in combat!"
— In-game description

Gestures is a feature in Call of Duty: Infinite Warfare. By earning them, players are allowed to select a gesture and applying it to their Combat Rig and then being allowed to perform it in-game. It is done by selecting left on the D-pad on console.

Gestures allow you to perform in game movements with your hand, such as playing Rock, Paper, Scissors or doing a "Vulcan salute". They can be used after a match ends so if you get the final kill you can quickly perform one after to show it off during they killcam. They are generally used for comedic purposes.
