I can tell you how to stop a tank.
Anyone who has driven a tracked vehicle knows this too (Stay out of the F&**$% wire).
Lay down a mat of woven wire and let the tank run over it, the cleats of the tracks will pick it up and reel it in to the tracks, enough wire will turn a tank into a pill box. It can create something that resembles a cable. And wire that is laid flat on the ground is damn hard to see through a periscope.
I saw a M113 get in to concertina once, and it took 4 guys with wire cutters all day to get it out.
The second way is soft ground. At Ft Hunter Ligget one year, I saw Marine M-60s buried up to their turrets in soft sand, Chaparrals and M113s buried halfway up their sides. The top of the ground was hard but the soil underneath it had the consistency of wet cement. The drivers did not know they were in to it until they felt the tank start to break through, (the soft spots were every where too) then the only thing you could do was floor it and hope you had enough power and speed to ride the wave out to solid ground. It didn’t work much. I’ve also seen an M88 retriever and two D-9 cats trying to pull the tank out. It took all day plus a real intrusting block and tackle setup from a 5 ton wrecker to get it done.
Saw a M113 buried 5 ft deep. It was really a lot of fun to watch. There was a bunch of city slicker officers running the show, (they didn’t have a clue) while a couple of us NCOs who grew up on farms and grew up pulling big pieces of stuck farm equipment out of the mud stood back and commented. We made one mistake though, the CW4 motor officer over heard us, he ran the officers off and put us work, but I digress.
If you put the two together it could be more effective, all you need is enough wire to cause a tank on soft ground to slip a little and the cleats will dig it in, in nothing flat. I know I’ve seen it.
Also a good chunk of hard wood, or a piece of railroad rail shoved between the road wheels can stop a tread real quick. If not break or throw it. I have also seen thrown treads from turning too short (Using the pivot steering) on hot asphalt or in deep/soft sand or gravel. The Tread balls it up under the road wheels then pushes the track off. Saw a M748 ammo carrier (M113 hull that looks like a pickup on treads) throw both treads in soft sand at the same time. No that is going some, we never could figure out how the driver did it since after loosing the first one, the thing was immobile.
But with a rifle Not unless its a rifle like they used in the Robocop Movie
