Wow, I was thinking about trying a MotW for the War Dog this weekend. I get online, and lo and behold there's a thread about the War Dog :o
Overall,it's not a bad design. But it's somewhat hampered by some WTF design choices, to say nothing of the errors in the original stats.
An idea for a modern upgrade: Using the original 3055 entry as a starting point, the erroneous engine weight matches a light engine. Go with that to improve survivability ^-^
