I will refer to an "attack" and an "action" button. I am calling it these instead of something more specific like shoot or melee because they change jobs. The attack button refers to shooting and melee while the action refers to taking cover and marking executions.
At the very start of the game you are ordered to get a gun. Walk forward, creeping up to an enemy, and tap the attack button while it is displaying a fist.
