It is provided in its original form to include Iraqi classification markings (i.e. Top Secret, Secret, etc.). These classification markings are NOT U.S. Government markings. ********************************************* Annex C Methods of delivery of toxic chemical agents and their characteristics Air methods Aircraft spray 1. Spray tanks in aircrafts (whether regular, guided, or combat) provide an efficient method to use a certain amount of the agent far better than any other weapon. 2. Persistent agents such as Mustard or VX can be launched from tanks in the slip-stream of the aircraft where the liquid shattered due to the extreme air into small droplets that fall towards the ground depending on its final speed. The large drops fall in the upwind sprayed area while small droplets fall slower and therefore are exposed to the effect of the wind for a longer period and move to a farther distance. As to the small droplets, they evaporate or spread before reaching the ground. However, it is possible to minimize this loss by adding a thickener to increases the agentÕs density and make large drops. 3. Spraying thick (viscous) or light (not viscous) liquids will show remarkable differences in the contamination level of the hit area. The surface of the spray area that is usually downwind, depend on the altitude and speed of the aircraft, wind velocity, the amount of agents to be sprayed, and the aircraftÕs position in the wind. Naturally, the upwind part of the sprayed area is the most contaminated area. 4. To get a result when spraying toxic chemical agents (non viscous), the process should occur at low altitudes and not exceed 150 meters. At higher altitudes, drops of a toxic chemical agent will evaporate, shatter, and become useless. 5. When spraying viscous liquids (toxic chemical agents) at low altitudes, the ground toxicity will be limited due to the very quick fall of all the viscous drops. This method is used only when severe contamination levels are required. Aircrafts that flight at low altitudes are vulnerable to anti aircraft weapons especially when flying over altitudes that are above 150 meters. Spray is unlikely from aircrafts at altitudes that are more than 150 meters. However, at very high altitudes (3000 meters or more), it cannot be controlled. 6. Low altitude spray that is vertically directed for the wind, may cover 1000 meters deep downwind for each aircraft. The contamination of the ground will certainly be sufficient to force the troops to take the necessary protective procedures. The length of the contaminated area depends on the cargo. It may range between one to many kilometers if the spray attacks were at low altitudes and the process occurred along the direction of the wind. Then, the contaminated area will be small but the contamination level will be more than the vertical spray towards the wind. The contamination level that is usually expected from the low altitude spray ranges from a fraction of a gram to many grams for each square meter. 7. The spray falls at a speed average of 300 meters / minute. This is not affected by the clouds. Spay can be easily identified if the aircraft is seen during the spray process. Otherwise, it would be very difficult to identify because the drops are very small. The fallout period is short and cannot be felt by any person even if the drops fell on uncovered skin. 8. Spray attack people mainly through the skin. However, drops may develop and be so small that they evaporate immediately and cause remarkable risks even of low volatility toxic chemical agents such as mustard. Spray drops may also be so large that they cannot penetrate shelters. Any head cover also gives a good protection. The spray attack may be less effective in cold weather where troops (that are not wearing protective equipment) are wearing thick clothing for protection from cold. This will automatically delay the penetration of the toxic chemical agents into the skin. It may even prevent them fully. Aircraft Bombs 9. The advantages of aircraft bombs are that they contain a large amount of the toxic chemical agent and they are so accurate that can be dropped in areas that are beyond the range of the ground weapons. It is also possible to direct a load on the target that is far lager than thee one that can be directed by normal artillery. The process of equipping aircrafts with toxic chemical agents (chemical ammunition) is usually easier than loading it to ground weapons. Massive bombs 10. Non persistent agents A massive bomb that weighs 1000 pounds and is filled with a non persistent agent may be made to explode in confrontation or at a very low altitude. Such bombs contain a very explosive substance (their force equals a medium explosive) with a chemical charge of 60%. Severe risks will develop in the explosion area due to contamination through the skin (in addition to the risks of shrapnel from the very explosive substance) due to drops and high concentrations of the vapors that occur in that area. The sudden reaches its peak due to the low explosion. The area above which there is a non persistent toxic chemical cloud will be relatively small and this is not the ideal way to use the agent.. 11. Persistent agents Massive bombs that are filled with persistent agents may be exploded at an altitude of some hundreds of meters. Contrary to artillery shells, shells cover a large area with liquid spray. A simple explosion to open the light cover of the bomb container is all that is needed since air velocity shatters the liquid that become falling sprays. An explosion may be reached in the air after calculating the fallout period from the high aircrafts and having recourse to valves that work with the change of the air pressure or the effect of the size of the liquid drop. The contaminate area on the ground resembles the one that occurs when spraying toxic chemical agents from the air or the shape of area will be almost oblong. This due to the fact that drops are launched from one source. Thus, a small and very effective area will form followed by larger areas but they are less contaminated towards the wind and both sides as well. Also, when spraying from aircrafts, the affected area will shrink and its contamination level will increase every time the launching area altitude decreases or the effective wind velocity decreases. If a large amount of bombs were dropped at the same time on a wide area, the result will be a reason to multiply the effect of each bomb. Cluster bombs 12. Cluster bombs include a container in which there are small bombs. They can be dropped from an aircraft in the same way massive bombs are dropped. A cluster bomb container is designed to open at an altitude that is appropriate to spread bomblets with wind velocity. It may reach 1500 meters. The container may consist of a reinforced box that is shattered by the aircraftÕs air current. Then, the bomblets disperse. The dispersion of the bomblets that weigh about one kilogram each cause the spread of the toxic chemical agent that is more regular and less costly than one single massive bomb. Bomblets may be filled with any type of toxic chemical agent. They may also be spread by using a propelled or explosive charge of TNT. The may resemble sometimes fireworks and contain spraying tools that release air that help the aerosols to fly. 13. The average between the weight of that agent (substance) and the weight of the bomb in castor bombs is slightly less than the average in the regular massive type. However, due to the agentÕs consistency when thrown by cluster bombs, the contamination area increases. As to the sudden impact that is caused by the cluster bombs, it is less than the one caused by the ground explosion regular bombs. This is due to the elevation of the explosion. Bomblets 14. Bomblets that are directly fired by aircrafts during a low altitude flight, hit a small area that has severe local risks. Filling these bombs with non persistent chemical agents is most probable. Large amounts of the toxic chemical agent are expected to be lost in the holes if the bombs were designed to cause contamination with the liquid or spray after a collision. The warning that is available for defense will be shorter than any other warning of an air attack at a low altitude. Other air weapons 15. Air missiles 30 mm missiles could spread an appropriate amount of the agent to the target due to its high fire range. They may be used to handle small but difficult targets by using non persistent chemical agents where a cloud injects its drops into the area that is reinforced against attacks with conventional weapons. 16. Air to ground rockets They are various types that range from a 2 Knot with a warhead that is half a kilogram wide and reaches large methods. They are in effect massive bombs with propellants. These rockets have a high speed when they hit the target. They tend to cause large holes. Thus, a large amount of toxic chemical agents is wasted because of mixing with the holes. This type of weapon is usually filled with persistent chemical agents. Since they are very accurate, they are used in handling the appropriate small targets Long range missiles 17. Missile heads that are usually larger than an air bomb are carried on a guided or ballistic missile. They are filled with any type of chemical agents. 18. Non persistent chemical agents They are formed due to ground explosions that hit and explosions that occur in the air at a low altitude. They resemble highly concentrated but local clouds. Therefore, they give us the best use of non persistent chemical agents. As to long range missiles, they carry a large load and there is big chance that they may not hit the target. Therefore, they may most probably be loaded with various types of small canisters clusters. The blast is timed to be in the air to be spread on a large area that can cover a circle with a half diameter of 1000 meters. The missile explodes at an altitude that may reach 1500 meters. Keep in mind that canisters reach the ground 10 seconds after the missileÕs explosion. 19. Persistent chemical agents They may be used in the same manner massive shelling is used. They explode in the air and have the same properties. However, due to the missileÕs high speed, the charge will disperse and spread to a large area if the anti-dispersers were not added to the missile. (Conventional) ground weapons Artillery shells General 20. These shells are distinctive because they fire the available artillery and do not need special training other than identifying the amount of bombs that are required for each duty. They can be fired at any target within the missileÕs range with the same accuracy. Concentrated shelling may be relatively and quickly planned and carried out. When the target is far from our troops, the direction of the wind is not important. On the other hand, the amount of agents in the bomblets is considered small (about 5% of the weight and this percentage increases with the increased amount. Therefore, there is a need for large amounts of ammunition in some cases. Explosive bombs with a non persistent toxic chemical agentsÕ charge 21. Highly explosive bombs that are designed to cause an effect from vapors. Therefore, air explosions are considered useless. The closer they are to the ground, the more effective. The charge may consist of 4 parts of the agent and a part of the explosives. Although the effect comes from the vapors, the secondary effect may be among the liquids that do not evaporate during the explosion in or around the bombÕs hole. The effect of their vapors remains for a number of hours. In addition, they are shrapnel of the bomb that may consist of half the effect of bombs with the same caliber. 22. The troops may cross or attack the targets that were hit by such ammunition (chemical) after taking all the appropriate protective measures (even if partial). However, occupying and remaining in these areas is not risk free. Usually, the constant danger is concentrated in the holes of the bombs. Using a large amount of explosives in such bombs affects the function of the toxic chemical agent since this cause their dissolution after explosion because of heat except for Mustard and Sarin that are sufficiently persistent. Using less than 105 mm bombs is not possible due to their small size. More than 155 mm bombs are considered very effective when used as separate shots. In order to get the most out of the sudden impact, they are fired in a concentrated way, a short time, and against limited targets. 23. Usually, these bombs resemble their similar others. The same valve is used for their explosion. Explosive bombs with a persistent toxic chemical agentsÕ charge 24. Ground explosion A chemical bomb can be used with small charges to reduce the dispersion of a persistent liquid chemical charge. Thus, substantial dangers lie contaminated spots, drops, and soil. The sound and shrapnel effects may be far less than the bombs or chemical bombs with a non persistent toxic chemical agent and that are of the same caliber. 25. Air explosion The charge must be very small and the explosion at a very low altitude to prevent it from becoming volatile drops. Base ejection shells 26. This type of shells is considered one of the best methods to spread toxic chemical agents to targets in the shape of drops or air sprays. The shell may be launched over the target or when hitting the ground. The explosionÕs altitude resembles that of smoke bombs or similar bombs . Air explosions are distinctive because they are very weak and may be clearly distinctive from very explosive bombs. The launched liquids may be seen a few seconds after the explosion. One bomb may affect the area in the shape of a feather (leaf) that is tens of meters wide (towards the wind) and hundreds of meters long. The toxic chemical agent will spread or shatter in them to the highest level of contamination where they reach about one to two grams for each square meter (1 or 2 gm / m2). The morphology of the ammunition will be high due to the inaccuracy in firing that is caused by the wind effects. 27. Carrier shells A carrier shell may be used to launch fireworks or aerosols generators that fall on the ground after launching the charge. A large part of it is not lost after being buried. It is unnecessary to make the generators charges limited to volatile toxic chemical agents since almost any type of toxic chemical agents may be used. Mortars 28. Mortars would have been considered very effective weapons for firing chemical weapons if it were not for their limited range. A bomb carries more that the artillery shell (10% of the charge). Their low speed when they hit a target reduces the risk of losing the toxic chemical agent in and around the bombÕs hole. 29. The main characteristics of mortars are the continuous and quick speed, high mobility that allows launching local and severe chemical attacks. These attacks may be mainly against people. However, they can be used to contaminate the ground especially vital paths . Mortar ammunition may be loaded with any type of toxic chemical agents. 30. Explosion by clashing with mortar bombs (chemical) is not unlikely. However, due to the slow primary speed of the mortar bomb and its high generator (almost vertical), an air explosion is more practical. Therefore, mortars may be more responsive than artillery to spread the drops or the detergents and give way to various chemical attacks. Multiple missile launcher (Artillery) 31. Free fall missiles are distinctive from other ammunition of the same caliber. When using multiple missiles, a wide area can be contaminated immediately. Due to the wide area hit by missiles, they are considered the weapons for targeting an area that may reach 1000 m2 for the large amounts. When using this weapon also, the shape and size of the area are different since they depend on the range. It is usually a circle in the main ranges. Missiles may be loaded with any type of toxic chemical agents. 32. The percentage of the agent is more than that in the bombs. It is more than 15 % of the charge. The missileÕs ranges may reach 15 kilometers. However, the fire and bustle may lead to losing the sudden impact that is provided by the other weapons even in the shorts ranges. Various weapons Contamination vehicles 33. A contamination vehicle mainly contains a tank that is mounted on the body and is filled with persistent toxic chemical agents that are sprayed by compressed air. The average load of a vehicle is enough to cause severe contamination to a lot of land 300 meters long and 15 meters wide. This method is distinctive since the agent is launched whenever or wherever needed provided that it is possible to secure these delicate vehicles in the appropriate time and place. Helicopters such hovercrafts may also be used for this task also. Chemical mines 34. Chemical mines may come in many shapes and types. A launched mine may throw a considerable amount of liquid (toxic chemical agent liquid) in the air. This may hinder the usual decontamination process of a mine field to a large extent because it contaminates the ground. Mines can also be used like containers of toxic chemical agentsÕ liquids. They are equipped with small charges that are controlled by electricity or safety fuse. Such mines are usually used in sabotage operations, bridges, and the evacuation process. Such mines may range between specially designed mines that contain 20 to 25 liters and simple containers such as cans. 35. One of the most important characteristics of a chemical mine is the local and severe contamination effect that leads to extreme danger when continuously persistent. Appendix (2) lays out a description of the chemical mines Direct fire weapons 36. Shots that shatter on the target (destructive bombs) When attacking solid targets such as tanks, charges that are loaded with a liquid agent are fired. When they hit the target, they shatter and cause severe contamination from the vapors and drops of the toxic chemical agents. Such charges (they may be light weapon charges) are very effective against targets that do not have protective methods (Air filters) or when sudden impact can be achieved. 37. (Piercing) Explosive bombs The blast that is necessary to explode any bomb of a chemical type may carry fumes of a toxic chemical agent and liquids spots through the cracks of the solid target that is resistant to ordinary ammunition. The most important advantage of these weapons is they may have considerable effects of the bombs that slightly misses the target. It is also possible for some penetration of the toxic chemical agent to occur against sites that are equipped with air pressure methods. Any type of artillery, rifles, or missile launchers may be used that can carry out this type of attack. 38. Piercing shells 15 to 25 mm piercing charges may be used to penetrate light armors that contain a small amount (up to 5cm3) of the toxic chemical agent. This amount can give the lethal dose in a closed area such as the tank. 39. Hand grenades and short range bombs Lethal toxic chemical agents do not have charges that are appropriate for small and short range shells. However, incapacitating toxic chemical weapons have appropriate charges such as Chloracetophenone and CS. These methods are usually used for training purposes and to control riots.

The purpose of using chemical mines that are filled with persistent nerve agents or blister agents is to prevent the enemy from using certain territories, delay the process of opening holes (paths) in minefields, and inflict casualties on the forces that cross the mine areas. Chemical mines may consist of chemical fields only or mix with mine fields against tanks, people, or both. Minefields become then chemically mixed. Chemical minefields 2. They may be used to contaminate vital locations where bridges and sabotage operations are underway. The explosion of chemical minefield must be fully or partially organized once the enemy is or about to enter the field area. In order to keep the contamination effect, it must be reinforced sometimes such as using the chemical ammunition through the artillery. 3. The responsibility of blowing up the minefield should be assigned to the commander who is responsible for protecting the field. When the wind direction is from the field towards our troops, precautions must be taken to warn our troops to take protective measures from toxic chemical agents vapors that blow with the wind. Minefields that are injected with chemical mines 4. In such fields, chemical mines are mixed with other types. The (chemical/regular) percentage of the mines depends on the movement of the enemy. Using regular mines reduces the speed of the troops that cross the area. This leads to increasing the time the troops were exposed to contamination with toxic chemical agents and to increase the possibility of contamination. Adding chemical mines to regular fields leads to complicating the process of opening holes (paths) where troops who open holes are forced to wear individual protective clothing. Description of a chemical mine (theory) 5. The description of a chemical mine is a theory only for the purpose of study and discussion. However, it is the description of a real chemical mine. 6. The concept of operating a chemical mine (about 5 liters) is when it is affected by either pushing or pulling a field wire, the container jumps about (3) three meters high due to the effect of a bullet from the exterior (it resembles the English antipersonnel mine, grade -2). It leads to contaminating individuals, equipment, and vehicles that exist in the explosion area. The mine that explodes with pressure for a small distance should be under ground to decrease the possibility of exploding due to other explosions (mines, artillery bombs) 7. The description of the mine may be as follows: a. Weight Empty: 4 kilograms Filled with 5 liters of persistent nerve agents: 8.5 Filled with 5 liters of blister agents: 10 kilograms b. Range Maximum half a diameter: 200 mm Maximum altitude: 200 mm 8. Density a. Minefields infected with chemical mines Mines are planted at a distance of 35 meters for all directions so that they lead to contaminating each field. Such a contamination is considered sufficient to guarantee the objectives that were mentioned for such a field. b. Chemical minefield Mines are planted 25 meters apart for all directions
