@didymus @NailBomb @GoodBoyUV There is no idea of an invasion of the Reich in July or August of 1941. This is also a terrible time to invade via Poland, as the rain season is at its peak. However, the main problem would be a total lack of logistics and, as you mentioned, officers.

The USSR would have been ready to confront Germany in mid 1942 with American backing, at the earliest. Which is why Barbarossa was a very reasonable decision, despite being carried out with poor intelligence and fundamentally flawed planning.
