one of the things that was stressed in tanks was to never make any turn while crossing a wire barrier, hit it straight on and maintain at least 15-20mph.
Why the no turn...military wire is made of fairly decent steel, when you slew your tracks, some of it will get caught up in the end connectors and be transferred to your final drive sprocket, get enough of it wound around the sprocket and it will shear bolts, pop the sprocket right off and immobilize your vehicle. Not a nice thing to have happen when in engagement range of a bunch of RPGs...
Now days (at least with the M-1s) it was taught that you hook up a mine plow to the front and then bull your way through.
This is one of the reasons why the field fortifications manuals also stress the need to deploy wire deep, in multiple layers and at angles to each barrier, when the tanks maneuver to breach the wire, you get flank shots at their armor and have an increased chance to snagging a tank or two.
the simple coils of concertina that get tossed out during a field ex won't slow a tank down....on a lot of FTXs, I've seen a platoon of tanks go balls out and run right over it.
As for wheeled vehicles...don't. One FTX in Germany, the engineers deployed a triple row of concertina, in the classic triangle pattern, a section of German Luchs hit the barrier at speed and wrapped an amazing amount of wire around their axles. Took their crews and several "volunteers" the better part of a day to get everything cut loose.
