Maoist Ballet

In the field, the shooter will be confronted with the problem of position selection, and he must be ready to meet it. In training I have always attempted to inculcate a critical evaluation of firing position. The principle is to shoot from the steadiest position available. A firing rest is always a good idea, and trees, fence posts, and rock outcroppings are more common than you might expect. Such are not to be counted on, however, and the shooter must cultivate the habit of instant position selection, adapted to terrain and time.

And tempo, perhaps.
