It was similar to the first but more rigid. Later, another XM40 prototype was designed. The initial prototype was heavily influenced by the M17A1/M17A2 masks and featured a dimple under the voice diaphragm for clearing the mask, a feature dropped in later prototypes. It was a very loose design, but it helped pave the way towards the development of the M40. In 1983, the ILC Dover company came out with the first prototype of the mask - the XM40. Learning from their mistakes, the Army decided to start over. The Navy and Air Force decided to develop the design further and finalized it as the MCU-2/P. These masks, however, had several problems with the panoramic eyepiece as well as the fact that the silicone rubber it was made of was vulnerable to persistent chemical warfare agents, which diffused into the silicone and eventually exposed the wearer to that agent. In the 1970s the Army experimented with two new masks, the XM29 and XM30 series. The M17 series lacked the latest seal design, leaving it susceptible to seal breakage during strenuous military activities.Surfaces in contact with the face weren't textured, and the mask was made from stiff blended natural and butyl rubber, making it stronger, but more rigid than previous masks. M17 series masks could be quite uncomfortable with long-term wear.The use of internal filters added bulk and weight to the mask. The M17 series M13 filters were difficult and time-consuming to change and couldn't be replaced while wearing the mask.However, the M17 series had a number of shortcomings: The M17 introduced a number of innovative features absent on the previous service masks, such as a voice diaphragm and a drinking system. 8.5 Preventative Maintenance Service Check (PMSC) Flash Cards.5 M40A1 (Universal Pattern Second Skin).The article was written by Robert Halvorsen based upon previous knowledge, but details were fact-checked against the. Losantin decontamination kits were still used until the end of the war.Ī great article on this topic can be found at, a comprehensive website filled with very complete information on the topic. This system used a plastic bottle of pre-mixed decontamination ointment with gauze pads to apply it. Realizing this, the Wehrmacht designed a new system and began issuing it in 1941. This process was cumbersome and time-consuming, both heavily undesirable factors when considering that immediate treatment of blister agent exposure is necessary to significantly counteract the effects of the agent. The paste was then spread on any skin exposed to blister agents using a gauze pad. The soldier was supposed to crush the tablet into a powder, and then add water to turn it into a paste. The first issue decontamination kit was a Bakelite container that held Losantin tablets. The gas cape was often strapped to the side of the canister for ease of use. Some canisters had a lining of aluminum sheet metal. The straps allowed it to be carried at the small of the back, which limited the potential unwieldy nature of the canister, keeping it out of the way for the soldier to use his weapon, go prone, and whatever else was necessary. The inside of the canister lid had a small container for gas mask antifog lens inserts, which in an emergency could also be used to replace broken gas mask lenses. The cleaning cloth was officially kept at the bottom of the canister, and was held down by a spring system designed for the carrier. The canister was waterproof when closed, and protected the mask from being jostled, bumped, and smashed due to its sturdy metal construction. The German gas mask carrier during WWII was a metal canister. Decontamination kits were also issued, in two types. Some were also issued with a rubberized 'gas cape', which was a chemical-resistant sheet that one was supposed to throw over themselves should blister agents be deployed. Every soldier was issued a gas mask, which was kept in a metal canister. Having learned from the chemical warfare of WWI, however, Germany wanted to keep its army protected against chemical warfare. Germany, the Soviet Union, and Britain all had large stockpiles of chemical munitions- the Germans had a slight edge in having the first nerve gases, but knew better than to push chemical warfare into the mix. Germany had an interesting approach to gas protection in WWII.
