1. General Ordnance Disposal Techniques

Many times an unexploded item of ordnance is "transported" to a safe place and exploded, this is an ideal situation and is not always the case. For example, many anti-personnel mines have devices that will detonate the mine if it senses a transporter beam. Most often, ordnance is blown in place using a "pop and drop" charge. A pop and drop charge is made by attaching approximately four meters of F-26 time fuse to an HL-60 fuse igniter, placing a blasting cap on the opposite end and placing it in a 200 gram block of Composition 8. The assembly is then placed on the ground next to the mine and the fuse ignited. Often this is not possible or practical, for these situations the following instructions will prove useful.

Equipment:

  • Nylon tool bag
  • Non-conductive crimping pliers
  • Non-conductive wire-cutting pliers
  • Blasting cap box w/ 30 caps, D-30 type
  • Utility knife w/ four blades
  • Fuse igniters, HL-60 type
  • Electric fuse igniter, ELC-44 type
  • Thirty 200 gm blocks of C8

2. Ammunition

Projectile and other munitions can typically be transported to a safe location and destroyed, or blown in place using a "pop and drop" charge.

3. Components

BLASTING CAPS The standard D-30 blasting cap is 7 cm in length and 1 cm in diameter. It consists of an aluminium casing filled with 5 grams of thermite.

ULTRITIUM A powerful chemical explosive, virtually undetectable by transporter scanners.

COMPOSITION 8 C8 is the most common plastique explosive in use. This gray-green material is easily worked into any needed shape. C8 requires a blasting cap to detonate.

F-26 FUSE F-26 time fuse consists of a quick burning compound formulated to burn at approximately .1 meters per second. Coated with a green polymer with a yellow stripe, F-26 time fuse is issued on spools of 20, 50, 100, 300 meter lengths.

PENTAGLYCERINE Pentaglycerine is one of the most potent conventional explosives in existance. A 200 gram block of Pentaglycerine has the equivelant blasting power of a kilo of C8. Reddish-gray in appearance this plastique explosive is easily worked into any desired shape. Pentaglycerine requires a blasting cap to detonate.

SENSORS Sensors are devices that respond to a stimuli. Many types of sensors are used by different armaments. these range from motion sensing, magnetic, infra-red, light sensing, pressure sensitive.

THERMITE DETONATING CORD Thermite is a compound that burns at a tremendously fast rate. Coated with a green polymer with a red stripe, Thermite cord burns at a rate of approximately 1800 meters per second. Thermite cord is ignited with a blasting cap.

IGNITING DEVICES There are two primary devices for igniting time fuse.

  • HL-60 Designed to be discarded after a single use, the HL-60 fuse ingniter is a cylindrical device 7 cm in length with a 2 cm diameter. It has a pull ring on one end and time fuse is inserted in the other.
  • ELC-44 A rectangular device 10 cm long by 8 cm wide by 4 cm thick, it has a twist handle on the top for creating an electrical charge to detonate a blasting cap.

4. Mines

5. Missiles

Section B.  Anti-Mekk/Anti-vehicle mines  Vibra-Bomb The Mark 86 Seismic sensory mine, or Vibra-bomb has a variable sensitivity, and when placed must be set to respond to a specific mass. The mass settings go from 10 to 100 tons in ten ton increments. The drawback to this type of mine is in the mass setting, for example a vibra-bomb set for 60 tons will not explode if approached by a 55 ton Mekk, and the same mine if approached by a seventy ton Mekk would explode while the Mekk is still 30 meters away. The Mark 86 is also equipped with an anti-transporting device and is not effected by electro-magnetic pulse devices. The Mark 86 seismic sensory mine is relatively easy to disarm, since there are no anti-tampering circuits. After uncovering the mine locate and remove the eight 6 mm screws on the side plate, after removing the side plate set the arming lever to "SAFE", remove the two 4 mm screws beside the arming lever and remove it. Remove both of the blasting caps from the charge, the mine is now disarmed.  Mark 57 Magnetic mine The Mark 57 magnetic mine weighs 50 kg. (110 lbs.) It contains a 1 kilo charge of Pentaglycerine behind 36 kg (80 lbs.) of teflon coated forged titanium darts designed to penetrate armor. The Mark 57 is designed to explode when it detects a mass of 20 tons or more over the mine, exploding like an upward pointing shotgun tearing through the thin underside armor of vehicles or Mekks. The mine is 90 cm. (36 in.) tall and 45 cm. (18 in.) wide. After the mine is uncovered, locate and remove the four 5 mm screws attatching the polymer plate to the top of the mine, remove the plate and locate the 5461 I/C board, this will disable the magnetic sensor, locate and remove the Class two 24 volt battery, this will prevent any accidental grounding while further disassembling the mine which may detonate the shaped charge at the base of the mine, at this time unplug the braid cable leading down to the shaped charge. Locate and remove the three 4 mm scrws holding the magnetic sensor array and remove the array, this will expose the shrapnel charge. The shrapnel charge is encased in a polymer basket for ease in assembly, remove the shrapnel basket and this will expose the shaped charge of pentaglycerine, gently up-end the mine to cause the shaped charge to slide out of the housing, remove the blasting cap from the base of the shaped charge and cut the green wire leading from the electic detonator to the blasting cap, the mine has been dis-armed.  Mark 59 Command detonated mine The Mark 59 command detonated mine weighs 145 kg. (320 lbs.) It consists of a 10 kg (22 lb.) charge of pentaglycerine behind 113 kg. (250 lbs.) of teflon coated forged titanium darts designed to penetrate armor with an effective radius of 60 meters. The Mark 59 mine is detonated on command by a 300 meter two-wire cord, the detonating command may come from a person, or sensor of nearly any type. Similar in construction to the Mark 57,  the Mark 59 is 110 cm (48 in.) tall and 60 cm (24 in.) wide. Once the mine is located, locate the two-wire command cord and cut the wires one at a time with a non conductive wire cutter. locate and remove the four 5 mm screws on the top of the mine, remove the top plate and locate and remove the class five 48 volt battery pack, this will prevent accidental grounding which may detonate the mines shaped charge. Remove the three 6 mm screws behind the battery mount, and remove the backing plate, this will expose the mines shrapnel package. The shrapnel charge is encased in a polymer basket for ease in assembly, remove the shrapnel basket and this will expose the shaped charge of pentaglycerine, gently up-end the mine to cause the shaped charge to slide out of the housing, remove the blasting cap from the base of the shaped charge and cut the brown wire leading from the electric detonator to the blasting cap, the mine has been dis-armed.  5. Missiles  Arrow IV Missile Weighing in at 181.4 kg (400 lbs.) the Arrow IV missile is one of the premier artillary weapons in the Maquis forces arsenal. Using a laser guidiance system, the Arrow IV homes in on illuminated targets causing tremendous damage on impact. The missile is 1.8 meters (6ft.) in length and 27 cm (11 in.) in diameter, and carries a 36.2 kg. (80 lb.) charge of  Pentaglycerine giving the missile a vast amount of destructive power. The Arrow IV carries no anti-tampering devices and is simple to disarm. Remove the four 6 mm screws located around the body approximately 15 cm (6 in.) behind the nose cone, the nose cone will slide out approximately 3 cm (1in.) before it is fully removed. Locate and remove the 11545 timing I/C circiut board, this will prevent the onboard computer from issuing the command to detonate if the missile is jarred. Remove the six 6 mm screws retaining the weapons onboard compter and electronics package, after removing the electronics it is safe to unplug the two braid cables from the warhead. looking from the top (nose end) of the missile, locate and remove the four 5 mm screws retaining the warhead access panel, with this done slide the panel upward to remove, now the firing circuit will be exposed,  remove the electric firing device from the warhead and the weapon is safe.    Long Range Missile The standard class 3 long range missile weighs 16.7 lbs.

The missile is de-activated by first removing the drive section. This is accomplished by removing the three 3.5 mm screws located between the fins around the body of the missile, the rocket motor will then slide out of the frame. If the missile has not been launched, the motor is rendered inert by removing the electrical ignitor located in the exhaust port. Next remove the two 2.5 mm screws retaining the nose cone, this will expose the target sensing array, remove the 9139 timing IC board, the missile is now inert. To disable the explosive remove the three 2 mm retaining screws inside the sensing array, this will allow removal of the sensing array mounting plate and expose the nose cone end of the explosive package. This is an 8.3 lb. block of Composition 8. Gently slide the charge out of the nose cone end of the missile. Note that there are two blasting caps in the charge, one at each end. Carefully cut the red wire on each of the caps, Now very gently slide the blasting caps out of the ends of the explosive charge. The charge should now be "safe".  Flare The Flare LRM consists of the standard class 3 LRM airframe converted to deploy a flare which burns for approximately 30 seconds. The missile is de-activated by first removing the drive section.
