Yeah, and I think it would be harder for the military to deliver for all of Canada. These truckers are not rent-a-mobs being lead by professional protesters. These are some of the real people that make a country go. When these people protest, it makes tyrants shit themselves.
Also remember that there is a lot more to driving a truck than shifting gears, leaving the stop sign in one piece when you make that right hand turn and backing up to the dock.
There is a little matter of knowing which streets you can use...low overpasses, bridge weights allowed, dead ends.... and where the heck is 2345 Black Street?
Military drivers will not have those skills.
