Operation and Function of the M72 Series LAW

Procedures on preparing the M72 Series LAW for use from FM 3-23.25

Before preparing the launcher for use, the firer inspects its overall
condition.

To extend the rocket launcher:

  • Remove the pull pin and rotate the rear cover downward so the front cover
    and adjustable sling assembly can fall free. Do not discard the sling assembly
    until after you fire the rocket.


Removing the Pull Pin


Removing the front cover and the adjustable sling assembly

  • With your firing hand, grasp the rear sight cover and with your nonfiring
    hand, grasp the launcher forward of the barrel detent. Pull your hands sharply
    in opposite directions to extend the launcher. To ensure the launcher is fully
    extended and locked, try to close it.


Extending The Launcher

  • To fire the rocket launcher, raise it slightly above shoulder level,
    rotate your body under it, and place it on your shoulder. Check the backblast
    area, pull the trigger arming handle to the ARM position, aim the launcher,
    and depress the rubber boot on the trigger bar firmly to ensure the launcher
    fires. If the trigger arming handle will not remain in the ARM position, the
    launcher is not fully extended. Pressing the trigger bar causes the firing pin
    to strike the primer, which ignites the black powder in the flash tube, which
    in turn ignites the propellant in the rocket motor.


Ensuring launcher is locked in the extended position


Firing The Launcher

DANGER:  WHEN OPERATING THE LAW, KEEP IT POINTED DOWNRANGE. ENSURE
YOUR WHOLE BODY IS CLEAR OF THE MUZZLE AND REAR OF THE LAUNCHER, AND ENSURE THE
BACKBLAST AREA IS CLEAR.
