Call of Duty: Warzone drops you straight into the action with up to 150 players competing on the same map. Verdansk may be huge, but you're sharing it with a lot of opponents and the encroaching poisionous gas is there to ensure that you'll never be too far from one another.
So, you won't have time amid the flying bullets to double check your control scheme and a mistaken button press can reveal your location or waste a consumable at the worst moment.
In order to be the best Warzone player you can be, you need to master your control scheme. While you cannot freely rebind any action to any button like on PC, you can switch between a number of controller presets with subtle changes in layout. If you don't want to stick to the default controls, study those layouts carefully. The default controller layout for Xbox is as follows:
Movement - Left Analog Stick
Sprint/Steady Aim - Left Analog Stick (Press)
Aim/Look - Right Analog Stick
Melee - Right Analog Stick (Press)
