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. ********************************************* [page-1] 1st Lieutenant 1st Lieutenant 1st Lieutenant Abdul Elah Hadi Hamza Mohammed Khalil Mazen Abdel karim 1st Lieutenant Suhail Mahmoud Shaker Second. In the semi-automatic pursuit (1) in the direction (30 degrees / sec) (2) in the altitude (18 degrees / sec) 11. The deviation in the side cross-beams. The cross-beams are parallel to the elongated beams when the gun is in moving position. There is a common clamp for the cross-beam in both the moving and the firing positions, which elevated the support of the cross-beams in the old gun. This resulted in retarding the gun's preparation procedure while the gun ammunition was being maintained during engagement, and its rotation in all directions. 12. The difference in the hoisting hook: A metal piece was added to the side of the hook to control the bullet pin during emptying operation which makes the emptying kit a one-piece kit as opposed to two pieces previously.

[page-3] Chemical Training Instructions -Second Section- [page-4] The differences between the Chinese made anti aircraft guns 57 mm model and the rest of the 57 mm anti aircraft guns There are some modifications and additions to the 57 mm guns and they are summed up as follows: The Electrical Firing Apparatus 1. This apparatus was added to the 57 mm model 59 for the purpose firing by battery guns with central control by the battery commander and simultaneously. By adding this apparatus it is possible to eliminate some of the guns personnel except personnel number(6) the filler, and ammunition personnel numbers ( 7, 8). The main objective of adding this apparatus is to concentrate the battery fire on the target, and eliminating the time difference between firing the gun and the moment the firing order is given, and pushing the foot firing pedal. Therefore, the time between issuing the firing order to the guns through the caller and receiving it by the personnel and pressing on the foot firing pedal is eliminated. The battery commander is therefore able to centrally fire the gun from the command post by pressing the electrical firing button of the battery commander. This apparatus is located on the upper part of the cradle and consists of the following parts: A. The magnetic coil B. A magnetic piece C. Delay Crowbar. (This crowbar is common between the electrical firing apparatus and the foot firing pedal). D. The conductivity box which conducts the electric power to the electrical firing apparatus. On the right hand side of the box there is a button which connects and disconnects the electric power to and from the electric firing apparatus. E. The electric firing button for the commander of the battery, and is connected through a cable on the main distributing box. [page-5] The Gun Rotating Disc 2. This disc is located in box number (11) of the battery along with four fastening nails, two are short and the other two are long. This disc is used to rotate the gun 180 degrees. In the event that the battery is transported on a narrow road and reaches a destroyed bridge where the gun cannot be rotated as it is hooked to the trailer, in this case the disc may be used to rotate the gun in any direction. How to Use The Disc A. Change the gun's position from moving to firing position without lowering the hoist so the fixed base of the gun would be on the ground. B. raising the barrel to the maximum angle of elevation (87 degrees). C. Placing the four fastening nails in such a way that the long nails would be placed in between the balancing arms of the rear axle (from the side of the pulling connection), and the short nails would be placed between the balancing arms of the front axle (from the side of [illegible] the barrel) D. Raising the barrel [illegible] E. Raising the gun by lowering the hoists for the purpose of inserting the turning disc under the middle of the gun base, and raising the tires off the ground. F. Putting the rotating disc under the gun. G. Raising the hoists to the maximum so the gun is supported on the disc, and thus the gun can be rotated in any direction. The [illegible] Target 3. the [illegible] Target for the Chinese made 57 mm gun mark 59 differs from the [illegible] target for the old 57 mm guns in the following dimension: [page-6] Keys: 1. Intersection of the left "Sadadah" 2. 1500 mm 3. Intersection of the right "Sadadah" 4. 120 mm 5. 431 mm 6. Intersection of the simple Sadadah 7. 165 mm 8. Intersection of Barrel Axis REMARKS: WHEN INSPECTING THE STRAIGHTNESS OF THE "AIMING PARTS " AND THE CONGRUENCE OF THE BARREL'S AXIS WITH THE SIMPLE"AIMERS, THE ZEROING TARGET MUST BE PLACED 50 METER AWAY FROM THE NOZZLE STAND. THE MINIMUM DISTANCE OF THE TARGET LOCATION IS 30 METERS. 4. THE MAXIMUM SPEED THAT CAN BE SET UP ON THE SPEEDOMETER OF THE CHINESE - MADE 57MM GUN, MARK 59, IS (350 M/ SECOND ). THUS THE AIR TARGETS WHICH HAVE A SPEED WHICH EXCEEDS THE SPEED OF SOUND CAN BE TARGETED. 5. THE MANIPULATION OF THE OLD RANGE DRUM TAKES THE SHAPE OF A CYLINDER, WHILE THE RANGE DRUM OF THE CHINES GUN TAKES THE FORM OF A GRADUATED RANGE DISC. THE MAXIMUM RANGE THAT CAN BE SET UP ON THIS DISC IS (70 HECTOMETER) INSTEAD OF (80 HECTOMETER). 6. SHORTENING THE LENGTH OF THE OLD GUN RULER WHICH IS (200 MM) LONG, TO MAKE IT (171.43 MM). 7. THE DIFFERENCE IN THE ODOMETER RECORDER CONTROL WHILE IN MOVING POSITION. IT CAN BE CONTROLLED BY RAISING THE RECORDER AND ROTATING IT (90 DEGREES) TO THE RIGHT OR TO THE LEFT, AFTER SETTING THE SPEED TO ZERO, THEN SETTING THE RANGE TO 25 HECTOMETER. 8. THE DIFFERENCE IN THE LOWNESS ANGLE. IT IS POSSIBLE TO LOWER THE CHINESE GUN'S BARREL TO (-5 DEGREE) ANGLE. AS A RESULT OF THIS FEATURE, THE HEIGHT OF THE ARMOR WERE LOWERED BY (13CM) IN COMPARISON TO THE PAST. [page-7] 9. Difference in the shape of the [illegible]: The [illegible] of the Chinese gun may be hooked together to make it easier to continue firing, and to help the filling personnel to control the position of the [illegible] in the filler. 10. The difference in some of the characteristics, we sum them up as follows: A. The weight of the gun in the moving position (4750 kg). B. The weight of the high explosive round (6.47 kg). C. The weight of the armor piercing round (6.45 kg). D. The weight of the barrel without the breech block (270 kg). E. The weight of the barrel with the breech block (324 kg). F. The number of [illegible] and the [illegible] for the barrel bore (24 [illegible] and [illegible]) First. The distance between [illegible] and [illegible] is (57 mm) which is the caliber of the weapon. Second. The distance between [illegible] and [illegible] is (58.8 mm). Third. The width of the [illegible] (2.45 mm). Fourth. The width of the [illegible] (5 + 0.03 mm). G. Length of the chamber (370 mm). H. Length of standard recoil from (300 mm - 360 mm) the maximum recoil is (370 mm). I. Length of the twisted part (3565 mm). J. Elevation of the gun in moving position (2.46 mm). K. The speed of visual firing (105 - 120 rounds/minute). L. The maximum oblique range for the projectile is (8800 m). M. The position of the muzzle reduces the barrel force by 38%. N. The front oil damper reduces the recoil force of the barrel by 32%. O. The angle of front axle rotation (45 degrees) to the right and to the left. P. The speed of the gun's movement: First: in the voluntary movement: (1) in the direction (24 degrees / second) (2) in the elevation (15 degrees / second) LN 156-95
