Have one ten-metre square marked out with cones; one man in the middle carrying a contact shield. The rest of your team distributed on the sides of the square.
One man comes into the square to engage the shield carrier. His task is to drive the shield carrier out of the square. He does this by coming into him in low body position, pumping his legs, taking small strides, binding all the time on the shield.
The shield-carrier does not stand meekly by but also tries to drive the clinging violet out of the square. When either one is driven out, the shield returns to the middle and then the next man from the next square side comes in to engage in combat.
So you work around the square in clockwise direction. When the shield carrier is exhausted, replace him. Body angle is important as is pumping the legs as are keeping on the feet and holding the bind.
Now put two shield-carriers into the square, make them bind onto one another and then send in two drivers at a time from the same side of the square to run in, bind together, and drive the shields out of the square, with opposition from the shield-carriers, of course.
