I'm still quite confused of the name of the launch vehicle

Zenit-2SB41.1 two-stage rocket plus Fobos-Grunt satellite equals Zenit-2FG (or Zenit-2SLB, but not Zenit-3F) rocket.
Cheers for the clarification!
The idea is that '3' requires some third stage in addition to basic Zenit-2SB type vehicle. In the case of Fobos-Grunt, there is no third stage per documentation, even if Fobos-Grunt ADU propulsion unit is a clone of Fregat.

 So what is unique about this rocket that makes it a Zenit-2SB41?

That it has a different fairing (like Zenit-3F) and probably a special payload adaptor to fit the Fregat-like propulsion module.

So what is different to a Zenit-3F / Zenit-2SB80?

They need to turn down the volume on the feed, the audio is clipped pretty badly.

powerplant is built on the basis of the proven Fregat, but it is upgraded a bit, so we worry of couse...

Here the Fregat (a.k.a. Flagman propulsion module) is part of the payload, whereas in Z-3F it is part of the launch vehicle.

I want to share yet another thing... A Lyulin-type instrument was installed on the Mars-96 probe, but as some of you probably know, the Block D of the Proton rocket failed and the probe fell back to Earth... The loss was devastating... The same scientist told me that they felt very upset...

Now we're hoping to gain the science we were hoping to gain from Mars 96... However, there's yet another stressful factor those days. Our govt cut funds from our Academy... The scientists are going on a protest tomorrow... As a person who works there  - I may join the protest too. We are afraid that we are facing closure. Our very success may depend on successful science projects. We are under extreme pressure. So I am praying everything goes on smoothly during launch... This launch will be unnerving and there are only two posibilities - either we will be cheerful or we will mourn the loss in tears...

But they are still independent of the Zenit. Both feature Fregat-SB (in this case 2003) and the same fairing?
