WORK IN PROGRESS Done Since I did not want to hijack/obscure the SITREP thread, I'm posting details and findings here, to put it up for discussion: Imho, yes. The report from 1942 is very interesting. It shows what information Allied intel branches had gathered, and also shows where German deception had at least partially worked: "German Smoke-Producing Units (Nebelwerferabteilungen) Six of these units have thus far been identified in the German Army. It is possible that eventually each Corps will include a smoke-producing unit. These have been identified in regimental chemical headquarters but only as administrative, non-operational headquarters." This reference shows that the Allies actually bought the pseudo purpose of the Nebelwerfer ("smoke throwers") units, as well as the whole Nebeltruppen (smoke troops) branch, which had already transformed into rocket artillery units. The US War Department's summary actually manages to pinpoint some of the details of the organizational structure of the (pre-war) Nebeltruppen (smoke troops), as it states that they were "regimental chemical headquarters", but then goes on and falsely identifies them as just administrative, non-operational HQs, where it then does not manage to reveal the general structure and the pre-war purpose of the Nebeltruppen as chemical warfare sections responsible for handling/firing chemical weapons and for decontamination. The major shift towards a rocket artillery role with the Nebelwerfer 41, and the fact that every unit in the German Army had a chemical appointee, was not gathered by the Allies either, at that point, obviously. There is another misconception: The report quotes a captured General order stating that the smoke cups on tanks were not successful. This is not entirely true. The external smoke cups (mounted on the side of the turret) were prone to damage caused by shrapnels and even rifle rounds, where then the electrical trigger could fail. Also, when empty, a crew member had to get out and reload the cups. While failed or damaged cups were not mass phenomenons, it was still disturbing for the tank crews, as smoke cup failures made tactical retreats somewhat more difficult. The new design envisaged the smoke rounds to be fired from inside, through a dedicated smoke cup hatch, which had a kind of flare gun attached to it on the inside (firing the same smokerounds as the external cups, iirc). The gun could be removed. At least the King Tiger received such a hatch. The report is from 1942, so - of course - Western Allies were less exposed to and less familiar with certain German assets or tactics than the Russians.
