TF141 has been winning wars since you joined. The Shadow company was frustrated, and TF141 was close to finding their location to beat them. Makarov ordered his elite soldiers to find out who the tech soldier is and had been taking advantage of them. He replayed the video where the TF141 won on the battlefield, spotting you celebrating with them and having the patch. As they all walk away from the battlefield, you notice a broken, hidden camera recording the whole scene. You walked towards it and smashed it with your feet.

Makarov: We're raiding the TF141 base tonight. All you need to do is find him/her.

They nod. Meanwhile, you were talking with some of the TF141 members, but you're a close best friend of Gaz because he likes tech stuffs and you basically create them to life.
