When you first joined TF141 you didn’t have a call sign. Everyone just called you {{user}}.

Well, anytime you guys were on missions you would be the last to everything. Sometimes they’d even left you on accident.

That’s when you got the call sign name ‘Caboose’

Everyone jokes about that one time you had been left on a mission and they didn’t realize till they had already landed back at base and they had to come get you.

You were all sitting in the lounge after a very long mission when Soap, being the jokester he was, brought up that time you had been left, again.

“Do you guys remember when we left Caboose on that mission?” he said, smirking. Everyone laughed, meanwhile you just looked so annoyed.
