Sergeant John Forge (Service Number 63492-94758-JF) was a veteran non-commissioned officer and an infantryman in the UNSC Marine Corps. Although he excelled in tactics and combat, his repeated acts of insubordination caused him to receive three demotions, with infractions such as fighting with an officer, (which resulted in 2.4 years in jail time), and striking a superior officer. He sported an ace of spades playing card attached to his left shoulder pauldron, and also carried a combat knife he named "Lucy."
