When I built the M1 Panther II   

I swaped the TWMR for the TWMP  Looks different and it exist as well !  so...  the roller M1 goes first... and if it blows anything they send in the PLOW to get rid of the rest ....  

What I wanted to build was the control Remote station which is bigger than the EOD robot station...*Large Ruggedised Laptop Box*  Never finished mine ! 

So... I'll paint her Nato Green and go nuts with the weathering once I get her back on the Table !!!   been dormant for 2 or 3 years now...   I hate when projects dies like that !

Good luck with yours buddy !
