Marksmanship shooters commonly visualize the sight picture, grip and trigger pull. They will practice this in dry firing.
Competitors in action shooting (ISPC, IDPA, ICORE, etc.) will sit down before each stage of a match and visualize their movements, positions, sight pictures and reload scheduling through the course of fire. I know one very competent shooter who goes almost trance like with the intensity of this visualization.
Smart Gun + 1 Battery + 3 Wires = Dumb Gun
PC = Agenda driven groupthink filter on reality.
