INTRODUCTION
1. Purpose and Scope
In Unconventional Warfare operations it may be impossible or unwise to use
conventional military munitions as tools in the conduct of certain missions. it
may be necessary instead to fabricate the required munitions from locally
available or unassuming materials. The purpose of this Manual is to increase
the potential of Special Forces and guerrilla troops by describing in detail
the manufacture of munitions from seemingly innocuous locally available mate-
rials.
Manufactured, precision devices almost always will be more effective, more
reliable, and easier to use than improvised ones, but shelf items will just not
be available for certain operations for security or logistical reasons. There-
fore the operater will have to rely on materials he can buy in a drug or paint
store, find in a junk pile, or scrounge from military stocks. Also, many of the
ingredients and materials used in fabricating homemade items are so commonplace
or innocuous they can be carried without arousing suspicion. The completed item
itself often is more easily concealed or camouflaged. In addition, the field
expedient item can be tailored for the intended target, thereby providing an
advantage over the standard item in flexibility and versatility.
The Manual contains simple explanations and illustrations to permit const-
ruction of the items by personnel not normally familiar with making and hand-
ling munitions. These items were conceived in-house or, obtained from other
publications or personnel engaged in munitions or special warfare work. This
Manual includes methods for fabricating explosives, detonators, propellants,
shaped charges, small arms, mortats, incendiaries, delays, switches, and simi-
lar items from indigenous materials.
2. Safety and Reliability
Each item was evaluated both theoretically and experimentally to assure safety
and reliability. A large number of items were descarded because of inherent
hazards or unreliable performance. Safety warnings are prominently inserted in
the procedures where they apply but it is emphasized that safety is a matter of
attitude. It is a proven fact that men who are alert, who think out a situa-
tion, and who take correct precautions have fewer accidents than the careless
and indifferent. It is important that work be planned and that instructions be
followed to the letter; all work should be done in a neat and orderly manner.
In the manufacture explosives, detonators, propellants and incendiaries, equip-
ment must be kept clean and such energy concentrations as sparks, friction, im-
pact, hot objects, flame, chemical reactions, and excessive pressure should be
avoided.
These items were found to be effective in most environments; however, samples
should be made and tested remotely prior to actual use of assure proper per-
formance. Chemical items should be used as soon as possible after preparation
and kept free of moisture, dirt, and the above energy concentrations. Special
care should be taken in any attempt at substitution or use of items for pur-
poses other than that specified or intended.
3. User Comments
It is anticipated that this manual will be revised or changed from time to
time. In this way it will be possible to update present material and add new
items as they become available. Users are encouraged to submit recommended
changes or comments to improve this manual. Comments should be keyed to the
specific page, paragraph, and line of the text in which changes are recom-
mended. Reasons should be provided for each comment to insure understanding
and complete evaluation. Comments should be forwarded directly to Commandant,

No. 1
PLASTIC EXPLOSIVE FILLER
A plastic explosive filler can be made from potassium chlorate and petroleum
jelly. This explosive can be detonaed with commercial #8 or military blasting
cap.
MATERIALS REQUIRED: HOW USED:
------------------- ---------
Potassium chlorate Medicine
Manufacture of matches
Petroleum jelly (Vaseline) Medicine
Lubricant
Piece of round stick
Wide bowl or other container
for mixing ingredients.
PROCEDURE:
----------
1. Spread potassium chlorate crystals thinly on a hard surface. Roll the round
stick over crystals to crush into a very fine powder until it looks like face
powder or wheat flour.
2. Place 9 parts powdered potassium chlorate and 1 part petroleum jelly in a
wide bowl or similar container. Mix ingredients with hands (knead) until a uni-
form paste is obtained.
NOTE: Store explosive in a waterproof container until ready to use.
Section I
No. 2
POTASSIUM NITRATE
Potassium nitrate (saltpeter) can be extracted from many natural sources and
can be used to make nitric acid, black powder and many pyrotechnics. The yield
ranges from .1 to 10% by weight, depending on the fertility of the soil.
MATERIALS: SOURCES:
---------- --------
Nitrate bearing earth or other Soil containing old decayed
materials, about 3-1/2 gallons vegetable or animal matter
(13-1/2 liters)
Old cellars and/or farm dirt
floors
Earth from old burial grounds
Decayed stone or mortal build-
ings foundations
Fine wood ashes, about 1/2 cup Totally burned whitish wood
(1/8 liter) ash powder
Bucket or similar container, Totally burned paper (black)
about 5 gallons (19 liters) in
volume (plastic, metal, or
wood)
2 pieces of finely woven cloth,
each slightly larger than bot-
tom of bucket
Shallow pan or dish, at least as
large as bottom of bucket
Shallow heat resistant container
(ceramic, metal, etc.)
Water - 1-1/3 gallons (6-3/4
liters)
Awl, knife, screwdriver, or ot-
her hole producing instrument
Alcohol about 1 gallon (4 lit-
ers) (whiskey, rubbing alcohol,
etc.)
Heat source (fire, electric
heater, etc.)
Paper
Tape
NOTE: Only the rations of the amount of ingredients are important. Thus, for
twice as much potassium nitrate, double quantities used.
PROCEDURE:
----------
1. Punch holes in bottom of bucket. Spread one piece of cloth over holes in-
side of bucket.
2. Place wood ashes on cloth and spread to make a layer about the thickness of
the cloth. Place second piece of cloth on top of ashes.
3. Place dirt in bucket.
4. Place bucket over shallow container. Bucket may be supported on sticks if
necessary.
5. Boil water and pour it over earth in bucket a little at a time. Allow
water to run through holes in bucket into shallow container. Be sure water
through all of the earth. Allow drained liquid to cool and settle for 1 to 2
hours.
NOTE: Do not pour all water at once, since this may cause stopage.
6. Carefully drain off liquid into heat resistant container. Discard any
sludge remaining in bottom of the shallow container.
7. Boil mixture over hot fire for at least 2 hours. Small grains of salt will
begin to appear in the solution. Scoop these out as they form, using any type
of improvised strainer (paper, etc.).
8. When liquid has boiled down to approximately half its original volume, re-
move from fire and let sit. After half an hour add an equal volume of alcohol.
When mixture is poured through paper, small white crystals will collect on top
of it.
9. To purify the potassium nitrate, re-desolve the dry crystals in the small-
est possible amount of boiled water. Remove any salt crystals that appear (step
7); pour through an improvised filter made of several pieces of paper and eva-
porate or gently heat the concentrated solution to dryness.
10. Spread crystals on flat surface and allow to dry. The potassium nitrate
crystals are now ready for use.

No. 3
IMPROVISED BLACK POWDER
Black Powder can be prepered in a simple, safe manner. It may be used as
blasting or gun powder.
MATERIALS REQUIRED:
-------------------
Potassium nitrate, granulated, 3 cups (3/4 liter) (see Sect. I, No. 2)
Wood charcoal, powdered, 2 cups (1/2 liter)
Sulfur, powdered, 1/2 cup (1/8 liter)
Alcohol, 5 pints (2-1/2 liters) (whiskey, rubbing alcohol, etc.)
Water, 3 cups (3/4 liter)
Heat source
2 Buckets - each 2 gallon (7-1/2 liters) capacity, at least one of which is
heat resistant (metal, ceramic, etc.)
Flat window screening, at least 1 foot (30 cm) square
Large wooden stick
Cloth, at least 2 feet (60 cm) square
NOTE: The above amounts will yield two pounds (900 grams) of black powder. How-
ever, only the ratios of the amounts of ingredients. Thus, for twice as much
black powder, double all quantities used.
PROCEDURE:
----------
1. Place alcohol in on3e of the buckets.
2. Place potassium nitrate, charcoal, and sulfur in the heat resistant bucket.
Add 1 cup water and mix thoroughly with wooden stick until all ingredients are
dissolved.
3. Add remaining water (2 cups) to mixture. Place bucket on heat source and
stir until small bubbles begin to form.
CAUTION: Do not boil mixture. Be sure all mixture stays wet. If any is dry, as
on sides of pan, it may ignite.
4. Remove bucket from heat and pour mixture into alcohol while stirring vigo-
rously.
5. Let alcohol mixture stand about 5 minutes. Strain mixture through cloth to
obtain black powder. Discard liquid. Wrap cloth around black powder and squeeze
to remove all excess liquid.
6. Place screening over dry bucket. Place workable amount of damp powder on
screen and granulate by rubbing solid through screen.
NOTE: If granulated particles appear to stick together and change shape, re-
combine entire batch of powder and repeat steps 5 and 6.
7. Spread granulated black powder on flat dry surface so that layer about 1/2
inch (1-1/4 cm) is formed. Allow to dry. Use radiator, or direct sunlight. This
should be dried as soon as possible, perferably in one hour. The longer the
drying period, the less effective the black powder.
CAUTION: Remove from heat as soon as granules are dry. Black powder is now
ready for use.
Section I
No. 4
NITRIC ACID
Nitric acid is used in the preparation of many explosives, incendiary mix-
tures, and acid delay timers. It may be prepared by distilling a mixture of
potassium nitrate and concentrated sulfuric acid.
Potassium nitrate (2 parts by Drug Store
volume) Improvised (Section I, No. 2)
Concentrated sulfuric acid (1 Motor vehicle batteries
part by volume) Industrial plants
2 bottles of ceramic jugs
(narrow necks are prefectable)
Pot or frying pan
Heat source (wood, coal, or
charcoal)
Tape (paper, elecrtical, mask-
ing, etc, but not cellophane)
Paper or rags
IMPORTANT: If sulfuric acid is obtained from a motor vehicle battery, concent-
rate it by boiling it until white fumes appear. DO NOT INHALE FUMES.
NOTE: The amount of nitric acid produced is the same as the amount of potas-
sium nitrate. Thus, for 2 tablespoonsful of nitric acid, use 2 tablespoonsful
of potassium nitrate and 1 tablespoonsful of concentrated sulfuric acid.
PROCEDURE:
----------
1. Place dry potassium nitrate in bottle or jug. Add sulfuric acid. Do not
fill bottle more than 1/4 full. Mix until paste is formed.
2. Wrap paper or rags around necks of 2 bottles. Securely tape necks of
bottles together. Be sure bottles are flush against each other and that there
are no air spaces.
CAUTION: Sulfuric acid will burn sn\kin and destroy clothing. If any is spill-
ed, wash it away with a large quantity of water. Fumes are also dangerous and
should not be inhaled.
3. Support bottles on rocks or cans so that empty bottle is slightly lower
than bottle containing paste so that nitric acid thet is formed in receiving
bottle will not run into other bottle.
4. Build fire in pot or frying pan.
5. Gently heat bottle containing mixture by moving fire in and out. As red
fumes begin to appear periodically pour cool water over empty receiving bottle.
Nitric acid will begin to form in the receiving bottle.
CAUTION: Do not overheat or wet bottle containing mixture or it may shatter. As
an added precaution, place bottle to be heated in heat resistent container
filled with sand or gravel. Heat this outer container to produce nitric acid.
6. Continue the above process until no more red fumes are formed. If the nit-
ric acid formed in the receiving bottle is not clear (cloudy) pour it into
cleaned bottle and repeat Steps 2-6.
CAUTION: Sulfuric acid will burn skin and destroy clothing. If any is spill-
ed, wash it away with a large quantity of water. Fumes are also dangerous and
should not be inhaled.
Nitric acid should be kept away from all combustibles and should be kept in a
sealed ceramic or glass container.
Section I
No. 5
INITIATOR FOR DUST EXPLOSIONS
An initiator which will initiate common material to produce dust explosions
can be rapidly and easily constructed. This type of charge is ideal for the
destruction of enclosed areas such as rooms or buildings.
MATERIALS REQUIRED:
-------------------
A flat can, 3 in. (8 cm) diameter and 1-1/2 in. (3-3/4 cm) high. A 6-1/2 ounce
Tuna can serves the purpose quite well.
Blasting cap
Explosive
Aluminum (may be wire, cut sheet, flattened can or powder)
Large nail, 4 in. (10 cm) long
Wooden rod - 1/4 in. (6 mm) diameter
Flour, gasoline and powder or chipped aluminum
NOTE: Plastic explosives (Comp. C-4, etc.) produce better explosions than cast
explosives (Comp. B, etc.).
PROCEDURE:
----------
1. Using the nail, press a hole through the side of the Tuna can 3/8 to 1/2
inch (1 to 1-1/2 cm) from the bottom. Using a rotating and lever action, en-
large the hole until it will accommodate the blasting cap.
2. Place the wooden rod in the hole and position the end of the rod at the
center of the can.
3. Press explosive into the can, being sure to surround the rod, until it is
3/4 inch (2 cm) from top of the can. Carefully remove the wooden rod.
4. Place the aluminum metal on top of the explosive.
5. Just before use, insert the blasting cap into the cavity made by the rod.
The initiator is now ready for use.
NOTE: If it is desired to carry the initiator some distance, cardboard may be
pressed on top of the aluminum to insure against loss of material.
HOW TO USE:
-----------
This particular unit works quite well to initiate charges of five pounds of
flour, 1/2 gallon (1-2/3 litres) of gasoline or twwo pounds of flake painters
aluminum. The solid materials may merely be contained in sacks or cardboard
cartons. The gasoline may be placed in plasticcoated paper milk cartons, plas-
tic or glass bottles. The charges are placed directly on top of the initiator
and the blasting cap is actuated electrically or by fuse depending on the type
of cap employed. This will destroy a 2.000 cubic feet enclosure (building 10 x
20 x 10 feet).
NOTE: For larger enclosures, use proportionately larger initiators and charges.
Section I
No. 6
FERTILIZER EXPLOSIVE
An explosive munition can be made from fertilizer grade ammunition nitrate
and either fuel or a mixture of equal parts of motor oil and gasoline. When
properly prepared, this explosive munition can be detonated with a blasting
cap.
MATERIALS REQUIRED:
-------------------
Ammonium nitrate (not less than 32% nitrogen)
Fuel oil or gasoline and motor oil (1:1 ratio)
Two flat boards. (At least one of these should be comfortably held in the hand,
i.e. 2 x 4 and 36 x 36.)
Bucket or other container for mixing ingredients
Iron or steel pipe or bottle, tin can or heavy-walled cardboard tube
Blasting cap
Wooden rod - 1/4 in. diameter
Spoon or similar measuring container
PROCEDURE:
----------
1. Spread a handful of the ammonium nitrate on the large flat board and rub
vigorously with the other board until the large particles are crushed into a
very fine powder that looks like flour (approx. 10 min).
NOTE: Proceed with Step 2 as soon as possible since the powder may take mois-
ture from the air and become spoiled.
2. Mix one measure (cup, tablespoon, etc.) of fuel oil with 16 measures of
the finely ground ammonium nitrate in a dry bucket or other suitable container
and stir with the wooden rod. If fuel oil is not available, use one half mea-
sure of gasoline and one half of motor oil. Store in a waterproof container un-
til ready to use.
3. Spoon this mixture into an iron or steel pipe which has an end cap thread-
ed on one end. If a pipe is not available, you may use a dry tin can, a glass
jar or a heavy-walled cardboard tube.
NOTE: Take care not to tamp or shake the mixture in the pipe. If mixture be-
comes tightly packed, one cap will not be sufficient to initiate the explosive.
4. Insert blasting cap just beneath the surface of the explosive mix.
NOTE: Confining the open end of the container will add to the effectiveness of
the explosive.

"RED OR WHITE POWDER" PROPELLANT
"Red or White Powder" Propellant may be prepared in a simple, safe manner.
The formulation describes below will result in approximately 2-1/2 pounds of
powder. This is a small arms propellant and should only be used in weapons with
1/2 in. inside diameter or less, such as the Match Gun or the 7.62 Carbine, but
not pistols.
MATERIALS REQUIRED:
-------------------
Heat source (Kitchen stove or open fire)
2 gallon metal bucket
Measuring cup (8 ounces)
Wooden spoon or rubber spatula
Metal sheet or aluminum foil (at least 18 in. sq.)
Flat window screen (at least 1 ft. sq.)
Potassium nitrate (granulated) 2-1/3 cups
White sugar (granulated) 2 cups
Powdered ferric oxide (rust) 1.8 cup (if available)
Clear water, 3-1/2 cups
PROCEDURE:
----------
1. Place the sugar, potassium nitrate, and water in the bucket. Heat with a
low flame, stirring occasionally until the sugar and potassium nitrate dis-
solve.
2. If available, add the ferric oxide (rust) to the solution. Increase the
flame under the mixture until it boils gently.
NOTE: The mixture will retain the rust coloration.
3. Stir and scrape the bucket sides occasionally until the mixture is reduced
to one quarter of its orginal volume, then stir continuously.
4. As the water evaporates, the mixture will become thicker until it reaches
the consistency of cooked breakfast cereal or homemade fudge. At this stage of
thickness, remove the bucket from the heat source, and spread the mass on the
metal sheet.
5. While the material cools, score it with the spoon or spatula in criss-
crossed furrows about 1 inch spart.
6. Allow the material to air dry, preferably in the sun. As it dries, rescore
it occasionally (about every 20 minutes) to air drying.
7. When the material has dried to a point where it is moist and soft but not
sticky to the touch, place a small spoonful on the screen. Rub the material
back and forth against the screen mesh with spoon or other flat object until
the material is granulated into small worm-like particles.
8. After granulation, return the material to the sun to dry completely.
