23. • Excellent penetration ability
• Lethal after-armor effects
• Extremely destructive
• Penetrates more than 14 inches of armor
• M136 is issued as a round of ammunition rather than
as a weapon.
• Should be inspected at the time of issue and before
use.

24. Ammunition Effects
Impact
The nose cone crushes; the impact sensor activates the fuze.
Ignition
The piezoelectric fuze element activates the electric detonator. The booster
detonates, initiating the main charge.
Penetration
The main charge fires and forces the warhead body liner into a directional gas
jet that penetrates armor plate.
After-Armor Effects (Spalling)
The projectile fragments and incendiary effects produce blinding light and
highly destructive results.

25. INSPECTION
Rear Seal :
The rear seal, a brown acrylic plastic plate inside the venturi, is in place and
undamaged.
Transport Safety Pin:
The transport safety pin is in place and fully inserted. The lanyard is
attached to the transport safety pin and the launcher. The lanyard should
already be wrapped around the launcher clockwise and the transport safety
pin inserted in the retainer hole counterclockwise.
Cocking Lever:
The cocking lever is present and in the SAFE (uncocked) position.
Plastic Fire-Through Muzzle Cover:
The plastic fire-through muzzle cover is in place and undamaged. If it is
torn or broken, cut it out and check the launch tube to ensure it is clear of
foreign objects. Remove any that you find by turning the tube muzzle
downward and gently shaking the launcher.

The most recent version of common CIED mistakes are:
Establishing route patterns
Relying on up armor to “find” IED’s
Moving (straying) from swept lanes
Establishing other patterns
Failure to check vulnerable areas
Failure to conduct proper threat analysis
Failing to use or improper use of CIED equipment
Failing to sweep for secondary IED’s or command wire after a find
