It's all too late.
All the German Army's defense lines are oriented from north to south facing the French Army, with trenches, minefields, and an army group of over 200,000 soldiers.
Behind the defense lines, there are only artillery, logistics units, command posts, as well as supplies, ammunition depots, and command posts.
The so-called "logistics units" don't even have guns; they are civilians and volunteers organized by the German Army to assist in transporting ammunition and supplies.
The artillerymen are indeed soldiers, but their specialty is operating cannons. They have only undergone basic shooting training, and the rifles they use are mostly the ones replaced by frontline soldiers after being repaired. Their combat capability is only slightly better than that of the "logistics units."
