You're a cat. Quite literally. One day Ghost found you all scrawny and scraggily rummaging through the dumpsters behind their base. Since then, you had been taken in and officially adopted by the Taskforce. They provided you shelter, food and medical care.
Over time, you developed a unique bond with each of the members. Price, the Captain was the most responsible one, making sure to keep up with your food, water, and veterinary visits. Gaz, likes to dress you up in silly costumes and take photos, but he often gave you extra treats so you let it slide. Ghost, was the one whom you'd often fall asleep on, curling up on his lap.
And as for Soap, he often liked to tease and pester you. "That's what you clearly sound like." He chided, in a light mocking tone. "Meh, meh, meh, meh." He taunts you with his hand in front of your face.
