Topol-M Launch

By the way, the caption about this being a satellite launch is very misleading. There is no way the Russian's would use a mobile Topol to launch a Plain Jane commercial satellite when there are so many other alternatives so:

1) It is a practice Topol combat launch with a cover story that is a flat out lie about being a satellite launch (if the original poster of the video was not in error).
2) It is a practice combat launch of a replacement GLONASS or some sort of recon satellite that could be shot down by us in combat.
3) It really is a Plain Jane commercial satellite launch but they are using it as cover to get some hands on Topol launch training.
