Chris,
In the process of posting the picture, I lost my message, so here goes. This is showing two simple examples of using holdfasts or earth anchors, they are shown in the pic as xxxxx. You can then go on to the more complicated layouts known as Compound-Direct and Compound-Indirect. The number of holdfasts required is worked out when you calculate the load, using weight of casualty, whether wheels or tracks are locked, ground type and conditions, gradient, etc.
