u/Dry-Extension-7378

I am looking at the 423 Scythian Griffins. I looked at their recruitment video here posted about 6 months ago, but now I see that the recruiter's account u/423_UAV_UA has been banned from reddit. I am hoping this isn't a red flag. Does anyone know what happened? And does anyone have experience serving with them?

Also for the 411 Hawks? Or other good SBS units?

Those two seem to have a good reputation, but some newer information is always welcome.

Bonus question: there seems to be disagreement here whether you have to do BZVP or not if you go the SBS route... any updates?

Thanks

Who is entitled to UBD status?

I am asking because I am speaking with some recruiters and will either go into drones with SBS or a rear position as a mechanic. I still haven't decided. SBS work will be closer to the zeroline so I am sure to receive it but with mechanic work, maybe not? Does it even matter? Will everything be recorded in my green book when I join?

Bonus question: apart from green book being AFU and red book NGU, what is the difference?

Thanks!
