I want to stress the documented need for the operator to stop the MV-4 before walking along its tracks to maintain the line-of-vision required to control it appropriately.

This picture shows the chevron tracks left by a flail and the dust-covered broken rocks left behind. On the bottom left is a V69 bounding fragmentation mine lying on its side and crushed into the ground. It would not be safe to step on that - so even the tracks should never be considered "clear" after a flail has passed. This mine was crushed into the ground. There have been other examples where flails have thrown the mines around and some have landed in the tracks behind the machine. When the flail raises dust, the entire area gets coated and exposed devices can be almost impossible to see.

The MV-4 operator must scan the ground closely as he walks in the tracks to change position. To ensure his concentration, the machine MUST be stopped before he starts to move.
