Drumming Question For The Music Majors

[Aero]

I like the drumming in this song and there's a few parts where the machine gun percussion sounds pretty impressive. If you listen at around the 1:40 mark, what kind of notes is this guy playing and how hard is it to do?

just a drum roll. sounds like a single stroke roll. they are pretty easy actually.
