A GREAT MANY instances occur every year in which people are choked, some to death and others painfully but not fatally. There are a number of Jiu-Jitsu defenses or releases from choking, some more complicated than others. This one, involving a single, sharp, accurate blow is easy to accomplish and entirely effective. It has the added advantage, if sharply and correctly administered, of ending the trouble at once as the attacker has little fight left in him. Us this defense when your attacker is...

Basic Principles Comparison Of Chemical And Explosive Weapons

An understanding of the true character of chemical warfare can best lie approached by a consideration of the action of combat chemicals as compared to that of explosive weai> ons. Certain important differences between the effects of chemical and of explosive munitions emphasize the peculiarity and novelty of chemical warfare and suggest some of its potentialities. These differences are particularly noticeable in the mechanism of the action of chemical agents and their effects in terms of time...

Lacrimatory Agents

The first toxic gases employed in the World War were the lacrimators, i.e., sulwtances having a specific action on the eyes and producing a copious flow of tears and temporary blindness. In the concentrations used in battle, neither the eyeball nor the optic nerve was injured and only in rare eases (as when a soldier was so near a shell burst as to have the liquid chemical splashed in his eyes) was any corneal injury experienced. In fact, so transitory was the effect of these early lacriniatory...

Screening smokes may also be generated from candles, shells, bombs, or airplanes. When a smoke screen is generated from candles, the wind must, be in the proper direction to accomplish the desired result. It must usually blow toward the enemy.

The lower limit is not so important since, even if the wind did reverse itself, the screening smokes are harmless to personnel. Steadiness of the wind...

Definitions

We have said that chemical substances used in combat are designated as chemical agents. Of these agents, three distinct groups gases, smokes, and incendiaries constitute what is generally understood as the mat riel of chemical warfare. Gases are chemical agents which produce physiological effects. These agents are used in war to incapacitate military personnel. Physically they are often dispersed as liquids and not infrequently as particulate clouds yet the term gas has attained in military...

Future Of Incendiaries

Modern warfare has left little on the field of battle that is combustible hence suitable targets and opportunities for the use of incendiaries iu the Combat Zone are very limited and will become increasingly so as armies are mechanized. On the other hand, the military airplane has opened up a vastly larger field of application for incendiaries in the areas behind the battle front and in the hinterlands of the belligerents. To an ever-increasing degree the successful waging of modern war depends...

In general, the respiratory irritants wer< all solids with high melting points and negligible vapor pressures. They were, therefore, dispersed by heavy explosive charges, in the form of a finely pulverized dust. The particulate clouds thus created lasted only a few minutes in the open, and they were accordingly classed as nonpersistent agents. They were, however, immediately effective and readily penetrated the existing gas masks of the Allies. It was due chiefly to these properties that they...

Nitroamines And Related Substances

The nitroamines are substituted ammonias, substances in which a nitro group is attached directly to a trivalent nitrogen atom. They are prepared in general either by the nitration of a nitrogen base or of one of its salts, or they are prepared by the splitting off of water from the nitrate of the base by the action of concentrated sulfuric acid upon it. At present two nitroamines are of particular interest to the explosives worker, namely, nitro-guanidine and cyclotrimethylenetrinitramine...

Methods Of Projection

Regardless of the technical means employed, there are but three basic methods of placing chemicals on a target area. First, by releasing the chemical from containers installed in one's own front lines, and depending upon the wind to carry it to and over the target area. This may be called the method of release at origin. Second, by releasing from containers projected on the target area by some physical means, such as firing from a gun (chemical shell), dropping from an airplane (chemical bomb),...

Lunginjurant Agents Group Characteristics

The lung injurants were the second group of agents to make their appearance in the World War. They form a well-defined group, having many properties in common* and for that reason they were designated by the Germans under a siugle generic class Green Cross substances. In general, they were all liquids of relatively low boiling points and high vapor pressures. They, therefore, were volatile substances that formed i ion persistent gases upon release from their containers. Their principal...

Relative Casualty Value Of Gases

In order to determine the relative casualty value of the principal battle gases, it is necessary to take into consideration the amountB of each that were used in battle during the World War. Table XV shows the amounts of battle gases of each class that were manufactured during the War. Of the 150,000 tons of battle gases manufactured during the war, approximately 125,000 tons were used in battle and 25,000 tons were left on hand after the war in filled shell and in bulk storage, as indicated...

Future Of Smoke Agents

During the World War obscuring smoke proved its tactical value on land and sea and won for itself an assured place as a military weapon. Since the war the development of air force has still further enhanced the value of obscuring smoke, for not only are airplanes a means par excellence for putting down smoke Bcreens on the field of battle, but their power of observation has greatly increased the need for obscuration. So greatly has aircraft increased the facility of observing enemy dispositions...

Physical Classification

The physical classification is very simple and is based upon physical state or form of the substance under ordinary conditiona, i.e., temperature 68 F. (20 C.) and atmospheric pressure (760 mm. Hg). Thus, an agent is a true gas, if its boiling point is below ordinary atmospheric temperature, as is the case with chlorine (b.p. 28 F.). This classification as a true gas is not to be confused with the broad generic term gas, used to refer generally to toxic chemical agents, but means that the...

Group II White Phosphorus WP

One of the earliest and by far the most efficient material used in the war for generating artificial smoke was phosphorus. This element exists in two allotropic forms white phosphorus and red phosphorus. White phosphorus, the normal and common form, was discovered in 1669 by the German chemist, Brand, who noted that it is spontaneously inflammable at ordinary temperatures and burns with a dense white smoke. While both white and red phosphorus were used in the war, white phosphorus was by far...

No m-nitrotetryl is produced if pure dimethylaniline is used in the usual process for the manufacture of tetryl. The amount of this impurity in the usual process depends upon the amount of monomethylaniline which may be present. A large excess of sulfuric acid tends toward the production of m-nitro compounds, but a reduction in the amount of sulfuric acid is not feasible for this increases the amount of benzene-insoluble material. m-Nitro-tetryl reacts with water, as TNA does the nitro group in...

Dissemination By Projectiles

While the theoretical economy of releasing chemicals on the target area is very large, as indicated above, the practical advantage is not nearly so great, for several deterrant factors enter into the projection and dispersion of chemicals from projectiles. In the first place, projectiles are not very efficient as carriers of chemicals, for their walls must be made thick enough to withstand the shock of discharge, and this greatly limits their chemical capacity. The efficiency of a chemical...

Incendiaries, the third member of the chemical arm, are striata nces used to set fire to enemy material in the Theater of War. Unlike gas and smoke, which are directed against personnel and are used chiefly on the field of battle, incendiaries are directed primarily against material, and their employment is not limited to the battle front, but extends to targets anywhere in the Theater of War that can be reached by bombing airplanes. Incendiaries may also be used to a limited extent against...

SiCl HjO Si OH i HCI

At a concentration of 0.20 mg. per liter, no further hydrolysis takes place, but an equilibrium seems to be established in which the hydrochloric acid liberated prevents further decomposition. In fact, when the hydrochloric acid becomes too great the above reaction may even be reversed and the amount of smoke actually diminished. If, however, the excess hydrochloric acid is neutralized by reaction with ammonia, hydrolysis of the silicon tetrachloride proceeds smoothly SiCL + 4NHi + 4H,0 - Si...
