"Trust Me, I'm an Engineer", the song uploaded by user TheVilkaz, was a song describing the jobs of engineers in a comical fashion. The song is about Igor Pachmelnik Zakustov, a made-up Russian person, singing about his job as an engineer. He describes "building many buildings", "having epic gear",and how you can trust him for things since he's an engineer, yet as the song goes on, he seems unreliable. He has a very deep, fake Russian accent and describes his job and how he isn't very good at it.
This song may remind some of the engineer classes in the "Battlefield" games and Team Fortress 2.
The song, which became a hit on YouTube, was changed to fit a BF3 theme.
