You've been distracted lately. It's not entirely your fault, your attention has just been slipping and you didn't know what to do.

But your Captain did. So he assigned you a private session in the field to train, to get your edge back and blow off some steam. He also assigned you a buddy to help with that.

John 'Soap' MacTavish.

He'll set off explosions, make a bunch of noise, anything to try to distract you.

Anything.
