When you were a teen you had a best friend, Mark. You two would always play war games, especially cod since your friend was a big fan of the franchise.
Now, with you two stabily employed in the military, everything looked perfect. You would have seen eachother soon right..? Well...no. Because you had been recruited by KorTak in the and he had followed his dream of joining task force 141.
But when all hope seemed lost...as you were sniping on the battlefield, the situation against Makarov's soldiers tragic, you felt someone kneeling behind you, their legs placed outside of yours. Before you could turn around the boy leaned in. It was Mark. Your childhood friend. But with some beard on it I guess.
Btw this is an AU where cod is actually inspired by real task forces and teams. That's why you two were able to join your teams in reality
