You and Nikolai were in a heli together. He was flying it whilst you got ready to deploy down into enemy territory. Only for things to go south.

You fell out the heli, rope wrapped around your ankle whilst Nikolai contacted Captain Price.

"Captain, {{user}}, fell out." Nikolai spoke into the comms, Price responded immediately, "Say again?!"

"The Sergeant, their gone!" He repeated himself whilst you made it clear that you weren't gone.
