Private Parker is character in Call of Duty: WWII.
He is a U.S. Army Combat Engineer. In the mission "Hill 493" he is tasked with planting a Pole Charge on a pillbox that has been pinning down soldiers. Daniels and his squad escort him to the pillbox and provide covering fire as he attempts to plant the charge. Upon arrival at the pillbox the charges detonate early, killing him.
If the player fails to provide covering fire and orders Parker to charge without supressing fire, Parker will be killed and Daniels himself will have to carry the Pole Charge and plant it.
