The M821 HE cartridge (M252 only) is a British-made cartridge fitted with the US M734 multioption fuze. He knocks down the near aiming post and proceeds to the far aiming post. The M252 81mm mortar is a smooth-bore, muzzle-loaded, high-angle-of-fire weapon. This action breaks an internal sheet pin and internal wire, thereby disabling the proximity function. However, at temperatures above 32 degrees Fahrenheit and at angles greater than 1068 mils, the flight time is sufficient to permit arming. This ensures a maximum traversing and elevating capability after making the movement. Then it is removed from the bipod and laid horizontally on the ground at the dud pit until it can be turned over to ordnance personnel. (3) From this train, extend a starting train that will burn against the wind of single increments laid end to end. All elements given in the fire command are repeated by the squad. e. The squad leader picks up the aiming posts and sight. One-quarter turn on the adjusting nut equals one turn of the traversing handwheel. 4-12. As soon as the sight data are announced, the gunner places it on the sight. The American M1 81mm Mortar, like the upcoming M2 60mm Mortar, was based on a French design by Edgar William Brandt (1880-1960). He rotates the socket so that the open end is pointing in the direction of fire. Correct way to open an ammunition box. Red phosphorus cartridges (M252 only) are stored the same as HE cartridges. b. Standard A ammunition for the M29A1 mortar is Standard B for the M252 mortar (, Light green Yellow band with red markings. The gunner then kicks the barrel several times with his heel in an attempt to dislodge the round. Correctly applying and performing these duties enables the mortar section to perform as an effective fighting team. c. The moisture-resistant seal of the container is broken when the ammunition is to be used. (2) The M84 fuze is a single-purpose, powder-train, mechanical-time fuze used with the 81-mm M301A1 and M301A2 illuminating cartridges. It arms within a maximum of 2.50 seconds. The floating firing pin located within the primer has approximately 1/16 of an inch to move around. The mortar is then re-laid on the aiming posts using the traversing crank. 0.30, BROWNING, M1919A4, M1919A5 AND M1919A6 {TO 39A-5 AF-32} (S&I BY PROP SEE DETAILS, FOOTNOTES), GUN, MACHINE, CAL. Mount The pile is covered with a double thickness of tarpaulin. The sight bracket is attached to the buffer carrier, which is fitted to the traversing screw assembly. The ignition cartridge has a percussion primer and is assembled to the end of the fin assembly. Proximity (VT). He exposes 1 inch (25 millimeters) of cross-level shaft and folds the handle. .30 BROWNING, M1917 AND M1917A1; GUN, MACHINE, CAL. It is fitted with a safety wire and pin that are removed immediately before firing. General Dynamics Ordnance and Tactical Systems is the leading manufacturer of propellants for 60mm, 81mm and 120mm Mortar Systems. d. The M374A2, M374A1, and M374 HE cartridges are painted olive drab with yellow markings and are constructed from pearlitic malleable cast iron. If you look at the table above, you'll see that at 1.5km range, 120mm mortars have nearly 33% more dispersion than 80mm mortars.Try testing 80mm mortars and 120mm mortars at 1.5km against . (1) The M935 fuze has two function settings: impact and delay. on Amazon.com. The leg-locking handwheel must then be tightened by hand, ensuring the teeth on either side are correctly meshed. FT 81-AI-3 Firing Tables Mortar, 81mm: M28A1 and M29 Mortar 81mm Self propelled M125A1 and M125 Carrier, 81mm Mortar Tracked XM755 81MM M252A1. This is the inert PD fuze type "IR-81" used by the Italians for their 81mm mortar rounds during WWII. b. A safety latch located at the side of the recess is used to secure the ball. As a longstanding partner of armed forces around the globe, Rheinmetall supplies a wide array of mortar systems and ammunition. This cartridge is ballistically matched to the M374A2, M374A1, and M375 HE cartridges, and weighs about 9.12 pounds. The fuze contains a delayed arming feature that ensures the fuze remains unarmed and detonator safe for a minimum of 1.25 seconds of flight. The gunner is given a deflection change between 5 and 25 mils, either increasing or decreasing from the last stated deflection, and the command to refer and realign aiming posts. Lock The platoon leader commands the platoon and supervises the training of the elements. HE ammunition is used against personnel and materiel. a. It is a smooth-bore, muzzle-loading, high-angle-of-fire weapon used for long-range indirect fire support to light infantry, air assault, and airborne units across the entire front of a battalion zone of influence. The Mark 4 and 5 barrels were introduced during World War 2 and have a much increased range. The safety pull wire is removed just before inserting the cartridge into the mortar. Dropping may cause the propellant charges to ignite, causing bodily injuries. From introduction up to halfway World War 2 the ML 3-inch had a poor range of up to 1.45 km. Since phosphorus liquefies at about 100 degrees Fahrenheit, the ammunition is protected against an uneven rehardening of the filler. The cartridge weighs about 9.12 pounds. It has no safety pins or wires to reduce preparation time. Each round is stenciled with the ammunition lot number, type of round, type of filler, and caliber. The cartridge is painted light green and has red markings and one narrow yellow band. Designed by Thingsym. b. Features: The M252 81mm Medium Extended Range Mortar is a crew-served, medium weight mortar which is highly accurate and provides for a greater range (4,500 meters to 5,650 meters) and lethality than the previous 81mm mortar. It uses the M185 propelling charge that consists of eight increments fitted into the spaces between the fins and held by a propellant holder. a. Cartridges are shipped with a complete propelling charge, an ignition cartridge, and primer. Excess increments should not accumulate near the mortar positions but are removed to a designated place of burning and destroyed. I say 120s are bad because they suffer from terrible dispersion even when not shooting at 6km. The M252 81mm medium extended range mortar (see diagram below) is a crew-served, smooth bore, muzzle loaded, high angle of fire weapon system. The 0-second boss is wider and differs in shape from the other body bosses; the safe setting position is indicated by the letter "S" on the fuze body. Fuzes are not disassembled. Bear in mind that these are my personal opinions, experiences, and . They are painted light green with red markings and one narrow yellow band. (6) The primer cartridge is checked for damage or dampness. The 0-second boss is wider and differs in shape from the other body bosses; the safe setting position is indicated by the letter "S" on the fuze body. Light tree foliage and light vegetation affect the height of burst only slightly, but dense tree foliage and dense vegetation increase the height of burst. Army Publishing Directorate The 81mm mortar is a portable, mobile, medium mortar at the infantry's disposal. The cannon assembly consists of the barrel that is sealed at the lower end with a removable breech plug, which houses a removable firing pin (Figure 4-3). (7) When opening an ammunition box, the ammunition bearer ensures the box is horizontal to the ground, not nose- or fin-end up. The mortar should be within two turns of center of traverse when the task is compete. d. The squad leader supervises the squad drill and is responsible for supervising the laying out of the equipment as shown in Figure 4-6. He positions the lower barrel clamp against the lower stop band on the barrel and secures the upper barrel clamp. In addition to loading, he swabs the bore after 10 rounds have been fired or after each fire mission. mortar, 81-mm: m29a1 and m29; firing cartridge, he, m374a2 and m374; cartridge, wp, m375a2 and m375 (s&i by prop see details, footnotes) ardec: ft 81-al-4(abr) active: 12/24/1970: firing tables for mortar, 81mm, m29 and m1 firing cartridge, illuminating, m301a3 with fuze, time, m84a1, height of burst, 600 meters (s&i by prop see details .
