Mission: Blue Team, flair shooter Easter egg?

So I’ve been playing this game and now I’m in my research mode. I’m playing the level Blue Team and I’m encountering these weird shapes: first time u see it is when u see that prowler class ship just outside the window. At that very first window look down, u will see the that shape. Now, when u fly the banshee for the first time in that mission go down, go to the middle bottom part of the ships round hull, park your banshee and walk against it.
When I do this flails shoot out for a short period of time, anyone know what this is?
