Serial numbers intelligence

Nice article, but certain paragraph made me uneasy: "By 1941-42, the allies knew that US and even British tanks had been technically superior to German Panzer tanks in combat, but they were worried about the capabilities of the new marks IV and V. " Oh really. I remember that US combat manual (or whatever they were called) from the era recommended a Tiger should be engaged by at least four Shermans. Assuming Tiger was waiting for them coming by the road, the first one was to be destroyed by the first shot, then the next one or two while they were getting closer to German tank, and finally the fourth had a chance to outmanouver the Tiger (they really sucked in dancing, from what I have read) and pack it a shot in the back from close distance. Sorry for nitpicking. Perhaps my memory comes from alternative reality, but it rhymes with data claiming that number of M4 Shermans produced during 1942-1945 period was almost 50000. As of the problem itself, here are some links. It is called "German tanks problem". https://news.ycombinator.com/item?id=20318184 https://www.eadan.net/blog/german-tank-problem/ https://en.wikipedia.org/wiki/German_tank_problem
