DOW G1 is not normally advised. Those 3 tanks in Gr Sth Germany are better used assisting in France.
Getting Russia down is the one and only objective Germany has in that game. So DOW1 on Russia is a but risky but a valid strategy because it take several Russian units out.
In order to compensate the missing tanks Germany should definitely let 111 or 110 go or even both seazones to get firepower at France with the Luftwaffe.
Exposing air to the French AA is a calculated risk Germans can definitely take.
It is a general mistake that beginners stretch the German forces too much at G1 (often attacking Normandy and SF that turn). Diluting the France attack to 90-95% odds not yet understanding that 95% and 99% makes a HUGE differences. You could describe it in other words: 95% is failing 5 times as often as 99% and even more important: winning is not everything. Germany taking France with 1 tank remaining is a pyrrhic victory and Germany is almost lost when losing almost all ground units in France G1.
