Umm, over 100% rear armor buff and 0.5 front armor buff.
Are all these 'kubel is fine' people even played the preview?
Thing is unkillable by inf unless jumped by a squad with at nades and decaps your map in no time.
Seriously?
Check my replay with Brad(the guy that should know how to abuse this the most) that I just uploaded a few days ago on the preview.
I had one RE squad almost solo the kubel from the front at the beginning ON THE OPEN SIDE of the map while taking fire the entire time. A WELL microed kubel I might add.
Later I'm pretty sure I killed his kubel the same way I've killed Them for a year and a half now, before the 5 min mark.
It doesn't suppress. It does pitiful damage. All it takes is one inf squad to send it into infinite reverse mode or it has to fall back and repair. Either way, it's not solo capping the whole map unless you let it.
