The problem with military gear is that it requires too much rear area support. If the tires aren’t a common tires then one flat and you have a pile of scrap metal. If the engine isn’t a common one then same thing if any part fails. When it comes time to change the oil and air filters if you can’t get replacements at the NAPA auto parts store then you’re in trouble once more.
If the vehicle is top heavy, how many drivers in your town are fully capable of knowing just what side incline will the vehicle safely traverse? Have you ever driven a two ton truck that weighs as much as a ten ton truck? With armor plating that’s what these things are like.
If we ever do have CWll (and I pray we don’t) let the military operate the military equipment and let us civilians determine how to mess with their supply lines.
Each Militia will have to establish their own operating procedures.
