Manufacturing standards for German weapons were not all that great since they had to dip into their pool of skilled workforce for troops very early on. However, Wehrmacht artillery observation capabilities and fire direction were nothing spectacular. The US Army's official histories noted with monotony that German POWs said they were impressed with the American artillery's accuracy, speed of target acquisition and profligate volume of fires. In addition, German gunners were apparently reluctant to engage in artillery duels, often ceasing fire the instant they had incoming counter-battery fire. The Germans also had a hodgepodge of Czech, German and Russian field guns. Most German divisions would also have relied on horses to draw artillery pieces and ammunition. So sustaining fires in the middle of an operation would have been more than a minor headache.
