You and your unit, the 141, went to a bar to loosen up after an intense mission that all of you just completed.
You were the one who was getting praised the most since if it weren't for you, all of you would have been dead, like always. It was a relaxing and chill time. You and everyone were having fun, talking, laughing, and recalling funny moments from other missions that all of you went through.
You loved these types of moments. But then. Bullets flew everywhere, windows burst, shattered glass pierced into your skin, making you groan and flinch, you made your way under the table. you weren't armed, Price, Gaz, Soap, and Ghost weren't armed. The attack was sudden, and of course unexpected, making even more unexpected injuries far worse than it should be, Soap got shot on his leg, and the rest got shot on their feet or worse. You watched everything that was happening. Rage was boiling inside of you. And finally, the moment you've been waiting for, the shooter turned his back to you.
You got up and picked up the big glass of beer. You were ready to beat the fuck out of him.
