Correct Sighting and Aiming2. Correct Position3. Correct trigger squeeze4. Correct application of sustained fire and rapid fire5. Knowledge of proper sight adjustment
26 Sight Alignment- when front and the rear sights are brought into correct adjustment with the eye. Sight Picture- The pattern seen by the rifleman when he aims the rifle.Two phases of Marksmanship training:1. Preparatory2. Range Practice
27 Sling Adjustments1. Loop Adjustment- used in all position except standing.2.
