A-2-1-91 Attacking Fuzes Flashcards
What is the preferred method for disposal of unexploded ordnance?
To destroy it in its original position by demolition
This method eliminates the need for a Render Safe Procedure (RSP).
What should be done when devising an RSP on damaged ordnance?
Radiograph the fuze to determine the arrangement of internal components
This helps in devising an effective RSP.
What is the wait time before approaching a dud-fired grenade?
30 minutes
Dampness or deterioration may prolong burn time.
True or False: All mines are suspected to have provisions for a booby trap.
True
Care must be taken to rule out a booby trap before removal.
What is the most utilized render safe tool?
MK 2 MOD 1, Caliber .50, Dearmer
Its applications have been extensively explored.
What effect does varying standoff have when using the MK 2 MOD 1 Dearmer?
It fluctuates slug speeds upon impact
Lower velocity results in less shearing and more jamming effects.
Fill in the blank: The angle of attack can change the effect of slug interactions uniquely to the _______.
[design of the fuze]
What is the purpose of the MK 171 MOD O Lightweight Disposable Disrupter (LIDD)?
To supplement the caliber .50 dearmer for simultaneous or sequential firing
Useful in rapid clearance operations.
What does the Tape and Line Technique accomplish?
Separates the fuzing from the main charge by remote means
Requires an additional procedure to RSP the live fuze.
What is the function of the MK 1 MOD 3 Remote Wrench?
Separates the fuzing from the main charge by remote means
Requires additional procedure to RSP the live fuze.
What is the main purpose of the MK 88 Shape Charge?
Disrupt integral electronics or mechanical features of fuze
What is the role of the Main Charge Disrupter (MCD)?
To low order large items by consuming most to all of the main charge
Used as a rapid clearance tool.
What is the purpose of the Flexible Linear Shaped Charge (FLSC)?
To separate pressure plates from mines and sever thin-cased bomb fuzes
Includes various applications for different ordnance.
What is the wait time before approaching a Powder Train Time (PTT) fuze?
30 minutes
An additional 30 minutes is required after attempting an EOD procedure.
What does the MK 23/MK 24 EXROD target?
Extremely heavy materials/dense fuzes
Ideal for attempting base plate removal.
What is the recommended action for any movement of armed or suspected armed items?
Perform remotely
This is crucial for safety.
What is the effect of moving an ordnance item suspected of containing a piezoelectric crystal?
May cause the piezoelectric crystal to produce a firing voltage
What is the MK 1 MOD 0 Demo Charge Container designed to destroy?
High-pressure air bottles
What are the applications of the MK 7 MOD 1-8?
Sever electric leads, disrupt firing train, gain access to internal components
Also puncture/destroy gas generators.
