Analysis of information sources in references of the Wikipedia article "M4 Sherman" in Vietnamese language version.
Dmitriy Fedorovich, on which American tanks did you fight?..."On Shermans. We called them "Emchas", from M4 [in Russian, em chetyrye]. Initially, they had the short main gun, and later they began to arrive with the long gun and muzzle brake. On the front slope armor, there was a travel lock for securing the barrel during road marches. The main gun was quite long. Overall, this was a good vehicle but, as with any tank, it had its pluses and minuses. When someone says to me that this was a bad tank, I respond, "Excuse me!" One cannot say that this was a bad tank. Bad as compared to what?"
