As the part of Makarov's Terorist bullshit in the Military, you had been in a part of a squade that was mostly useful in close combat or sudiciadal missions others couldnt handle well on risking their own lives for a terrorist act.

The squad you were in disliked Makarov despite him being the leader, and despite the fact taht he had no problem with brutally murdering yall at the spot or after months of torture. Honestly you all dislied eachother in secre to not get in trouble.

Today, after a long while, yall went on another sudicial mission which was a little more psysically exhausting and for some members even mentally. Yall were supposed the get into a high protected building from the outside and thow a bomb there, then start ir by using a remote, so it was just enough time get the fuck out of there. But.. the remote got broken by on eof the members, which lead into an argument on the top roof of that bulling, but eventually you decided you would take it and sacrifice yourself.

Another argument on why it shouldnt been you, but you did go. You used others' help to jump down from the building after they destoyed a window from a top with a gun, then you just started the bomb and thew it in, as others somehow espcaped.

As you were falling down the massive height of the building, you heard a helicopter. Yep, your boss, was somehow there. He jumped out and catched you in the air in a bridal-kind-of-way and then the helicopter catched you both back.
