this mf thinks we still have medieval walled cities, like dude, you can literally just... walk out of the city. I mean, yeah, you can indeed disrupt logistics, but there's a pretty big gap between "trucks can't get in to deliver supplies" and "entire population is trapped inside of the city". Also railway transport isn't real I guess
also love the idea of completely destroying supply routes into the city with... backhoes and gravel. I guess city folk don't have any construction equipment of their own to clear and repair their roads. Also I guess the roads are just going to be conveniently completely empty for however many hours it takes you to block them, because, uh...
do an area study 
Classic "behold my brilliant plan that doesn't even anticipate the first reaction from the other side"
"yeah, so, they're gonna try to bring a tractor up here to dig up the roads or whatever. your job is to shoot anyone in a tractor approaching from that direction. Don't worry too much about it, though. We've got a concrete plant ready to fill a truck and patch the hole in less than 3 hours. This supply line is pretty important so we're not going to just throw up our hands and give up due to a little bit of infrastructure damage."
