5-30. If the launcher is prepared to fire, but then is not fired, it should be returned to the carrying configuration by reversing the preparation procedure. After the launcher has been prepared for firing, it is no longer watertight. Therefore, when carrying the launcher, sling it over either shoulder with the muzzle (forward) end down. Only the rocket and rocket motor ignition system are waterproof.
• Return the trigger arming handle to the SAFE position.
• Remove the launcher from your shoulder, depress the barrel detent, collapse the launcher tube, and guide the front and rear sights into position.
• Close the rear cover, replace the cover pull pin, and replace the sling assembly.
To prevent injury, remove your thumb from the detent after collapsing the launcher 1/2 to 1 inch.
5-31. Many factors contribute to light antiarmor weapon marksmanship. Soldiers who combine these factors well, and continue to practice doing so, can retain their skills. The factors are grouped into four basic areas known as marksmanship fundamentals: steady hold, aiming procedures, breath control, and trigger manipulation. Instructions are given for right-handed firers, but the M72-series LAW can be fired from either shoulder by simply reversing the instructions.
5-32. Maintaining a steady hold involves holding the launcher as steady as possible while sighting and firing.
• To maintain the proper sight picture and sight alignment until firing, the firer must hold the launcher in a tight, comfortable position so that it becomes a natural extension of his body (Figure 5-22). Keep your elbows close to your body to help balance the weapon and prevent jerking or flinching when you fire. Place your left hand, palm facing upward, under the launcher near the muzzle and grasp the launcher. Firmly pull the rear cover into your right shoulder pocket.
5-33. Aiming procedures include placing the eye correctly, obtaining a sight picture, and aligning the sight. Combining these procedures is critical to correctly aiming light antiarmor weapons.
5-34. Before sighting the weapon, estimate the range. (Chapter 7 discusses range estimation.) Place your firing eye as close to the rear sight as is comfortable (Figure 5-23).
5-35. Align the sights correctly with the target. Position the rear sight so that your eye is near and in line with the peephole in the rear sight. Look through the peephole at the front sight reticle and place the range line that corresponds to the target's range on the target (Figure 5-24).
5-36. Position the front sight on the target. Stationary targets include those moving directly toward or away from the firer. Place the correct vertical range line in the center of the target (Figure 5-25, page 5-18). Slow-moving targets include those with an estimated speed of 5 miles per hour or slower, or those moving in an oblique direction. Place either the left or right lead cross mark on the vehicle's center of mass (Figure 5-26, page 5-18). Fast-moving targets include those with an estimated speed of more than 5 miles per hour. Place either the left or right lead cross mark on the leading edge of the vehicle (Figure 5-27, page 5-19).
5-37. Breath control is as important when firing a light antiarmor weapon as it is when firing an individual weapon. Breathing can cause a miss. To control breathing, the firer breathes deeply a couple of times, takes one last deep breath, exhales partly, holds his breath, and then sights and fires.
5-38. To fire the LAW, the firer must apply firm and steady downward pressure to the trigger with the fingers of his firing hand (Figure 5-28).
