You mean the same German army that relied on a 1,250,000 horses and even continued to use a horse cavalry?
From "World War 2, The Rest of the Story" by Richard Maybury: "A little known fact is that the Germans actually had two armies. One was the high tech mechanized force you have seen so often in movies. The aircraft, tanks, and artilleries are impressive, no doubt about it. But this force was small. It was only the tip of the spear. The rest of the spear, the main body of the army, was foot soldiers and horses. Yes, horses. When Hitler's massive invasion force was poised on the Soviet frontier in June 1941, it was at its peak. Lined up ready to strike at Stalin were 3,350 tanks. And 650,000 horses. Hollywood devotes a lot of film to the tanks, but how often have you seen the thousands of horses? Most of the horses were used as substitutes for trucks, but the Germans did have a horse cavalry division that was thrown against the Russians. (In contrast) when the British and Americans invaded Normandy in June 1944, they were fully mechanized, while the German army was still dependent on 1,250,000 horses."
You mean the same Germans who didn't even have the engineering skills to construct a single aircraft carrier?:

Meanwhile the U.S. built 146 of them in 44 months.
