1100 BC:- Offensive use of flame. The book of Judges 15:4, states that Samson caught 300 foxes, attached firebrands to them and set them out among the fields of the Philistines to burn their crops.
EARLY BIOLOGICAL WARFARE
600 BC:-Solon, the legislator of the Athenians, contaminated the River Pleisthenes with hellebores (skunk cabbage) to give the defenders of Kirrha violent diarrhea leading to their defeat. This is the first recorded use of plants as a source of chemicals for warfare.
431-404 BC;- Peloponnesian War. The first recorded use of poisonous and suffocating gases. During the siege of the cities of Platea and Pelium, the Spartans used wood, saturated with pitch and sulfur, set afire to produce sulphur

saturated with pitch and sulfur, set afire to produce sulphur dioxide gas. A sudden rain made the first attack fail but five years later the same type of attack was a complete success.
200 BC;- A Carthaginian general ordered a retreat, leaving behind a large quantity of wine poisoned with mandragora, a root containing a narcotic. After the enemy soldiers drank the wine and fell asleep the Carthaginians returned and massacred them.

• Biological warfare (BW) is the use of organisms that cause disease to harm or kill an adversary’s military forces, population, food or livestock.
– Living organic germs, like anthrax, are a major example of biological weapons.
BIOLOGICAL WARFARE
of biological weapons.– Byproducts of organisms, such as toxins. An example
is botulinum.
• Biological agents are much deadlier, pound for pound, than chemical agents. It has been estimated that 10 grams of anthrax could kill as many people as a ton of the nerve agent Sarin.

BIOLOGICAL AGENTS
Symptoms appear 12 to 72 hours after ingestion or inhalationInitial symptoms are nausea and diarrhea, followed by weakness, dizziness and respiratory paralysis, often leading to deathAntitoxin can sometimes arrest the process.
Botulinum toxin is a polypeptide (two peptide chains joined together by a disulfide bond).
Lethal doses are Lethal doses are estimated about 0.1 µg IV or IM. 0.8 µg inhaled, and 70 µg orally.
The toxin cleaves receptors needed by the neurotransmitter synaptic vesicle.

Anthrax Vaccine
The vaccine is a cell-free filtrate, produced by a strain of anthrax that does not cause disease. The vaccine contains no whole bacteria, dead or alive.
The vaccine was developed in the United States during the 1950s and 1960s for humans and was licensed by the FDA in 1970.
Anthrax Vaccine
Since 1970, it has been safely and routinely administered to at-risk wool mill workers, veterinarians, laboratory workers, livestock handlers and Service Members in the workers, livestock handlers and Service Members in the United States.
The vaccine is manufactured by one company, the BioPort Corporation, formerly known as the Michigan Biologic Products Institute (MBPI).

Advantages of Biological Weapons

Advantages of Biological Weapons
In October 1992 Shoko Asahara, headof the Aum Shinrikyo cult, and 40followers traveled to Zaire, ostensiblyfollowers traveled to Zaire, ostensiblyto help treat Ebola victims. But thegroup's real intention, according to anOctober 31, 1995, report by the U.S.Senate's Permanent Subcommittee onInvestigations, was probably to obtainvirus samples, culture them and usethem in biological attacks.
Access
On May 5, 1995, six weeks after the Tokyo subway incident, Larry Harris, a laboratory technician in Ohio, ordered Yersinia pestisfrom the ATCCfrom the ATCCMember of a white supremacist organizationAuthorities alerted when Harris impatiently inquired about his order.Currently, the CDC is charged with monitoring shipments of infectious agents.
Biggest Advantage
Killing efficiencyDepending on the toxin, approximately 1 gram can kill 10 million people.Botulinum toxin is 3 million times more potent Botulinum toxin is 3 million times more potent than Sarin.
Cost effectivenessTo affect 1 sq. km would cost approximately $2000 using conventional weapons, $800 using nuclear weapons, $600 using chemical weapons, and $1.00 using biologics.

Actions During an Attack
If threat forces attack with biological agents, theremay be little or no warning. This will depend on theIPB assessment. We cannot detect or identifybiological agents with our currently fielded detectorbiological agents with our currently fielded detectorkits and systems.
Soldiers in a unit automatically mask when there arehigh probability indicators of an attack to protectthemselves against contamination.

Biological Attack Indicators
Biological agents may be disseminated asaerosols, liquid droplets or dry powder.
Biological attack indicators fall into two groupsto indicate a high probability or possible attack.
NBCWNBCW
Attacks with biological agents will be very subtle iffavorable weather conditions prevail. Symptoms canappear from minutes to days after an attack has occurred.
Indicators may be the following:
Mysterious illness-many soldiers and civilians sick forMysterious illness-many soldiers and civilians sick forunknown reasons.
Large numbers of insects or unusual insects.Large numbers of dead wild and domestic animals.Mass casualties with flu-like symptoms, fever, sore
throats, skin rash, mental abnormalities, pneumonia,diarrheas, dysentery, hemorrhaging or jaundice.
NBCWNBCW
Indicators of a possible biological attack are any ofthe following:
Artillery shells with less powerful explosions thanHE rounds.
Aerial bombs that pop rather than explode.Aerial bombs that pop rather than explode.Mist or fog sprayed by aircraft or aerosol
generators.Unexploded bomblets found in the area.
NBCWNBCW
Imm Act
Putting on the protective mask and keeping the
clothing buttoned up protects adequately against
living biological agents.
An agent can gain entry through clothing using two
routes: one, openings such as button holes, zipped
areas, stitching, and poor sealing at ankles, wrist, and
neck and two, through minute pores in the fabric of
clothing.
NBCWNBCW
Immediate Actions
Putting on one's protective ensemble greatly
increases the protection level of the individual soldier.
Toxins, however, require the same amount of
protection as liquid chemical agents.
Since no rapid-warning, biological agent detection
device is fielded, consider any known agent cloud as a
chemical attack, and take the same actions prescribed
for a chemical attack.
NBCWNBCW
For collective protection, personnel must be housed insidea shelter with an efficient air filter system. Many buildings canbe converted into temporary shelters if cracks are carefullysealed and a filter system with a ventilating mechanism isinstalled.installed.
It must be emphasized that in order to counter a biologicalattack, protective measures must be initiated before an attack.The use of the NBCWRS is ' an effective and establishedmeans for giving advanced warning, along with intelligencedata provided by the intelligence community

Actions After an Attack
It is necessary to isolate soldiers showing symptoms ofdisease. This isolation helps prevent possible spread to othersif the disease is communicable.
It is also necessary to limit the number of personnel It is also necessary to limit the number of personnelproviding care to these casualties.
Treatment of live biological agent or toxin casualtiesrequires medical assistance as soon as possible.
An indication of a live biological agent attack is a largenumber of soldiers and civilians with unexplained illness overa short period.

The threat also has a wide variety of toxins.These can be dispensed alone or with othercarriers or agents.
Symptoms associated with some toxinsSymptoms associated with some toxinsmimic other illness or chemical casualtysymptoms.

Toxin symptoms may include any of the following:
Dizziness, mental confusion, or double or blurred vision. Tingling of skin, numbness, paralysis, or convulsions. Formation of rashes or blisters. Coughing. Fever, aching muscles, and fatigue. Difficulty in swallowing. Fever, aching muscles, and fatigue. Difficulty in swallowing. Nausea, vomiting, and/or diarrhea. Bleeding from body openings or blood in urine, stool, or sputum (spit).
