Yes. It is a military maxim you will lose if you want to fight the next war with the tactics and equipment from the last war. Your future opponents have been studying the last war and have invented all kinds of ways to destroy you if you use the same tactics again.
Modern military doctrine can be attributed to the Prussian General staff that defeated Napoleon III in the Franco Prussian war. Moltke the Elder was in charge of the Prussian army at the time. Moltke the Elder was a student of Clausewitz who literally wrote the book on modern strategy. But Clausewitz when he was in active service was not some world beating general. Clausewitz fought for the Prussians during the Napoleon’s time and was actually at one point a prisoner of Napoleon. Clausewitz and his boss Scharnhorst spent the rest of their careers developing a scheme to defeat Napoleons’ tactics of massive concentration at a single point. They developed modern combined arms with a logistical backbone of railroads.
