Thats what we are here for,ask away!!!Well first things tactically all the panzer crews were in full contact with each other as they had full radio gear in each Panzer.The russians didn,t have that till late in the war,if at all.Most german logistiucs were being carried by horse and cart all throughout the war.Germans were masters of camoflage,defensive tactics and ambushes.It was only the allied numbers that slowly wore them down.Each tank commander was trained to command on his own if he was seperated from the rest of his comrades.Also commanders and gunners tried to be kept together if one or the other were transfered due to the close work they had to do.Tiger tank drivers were hand picked and highly skilled to prevent breakdowns on the final drive gear.Heavy tank battalions were used as firefighting teams used to prop up defences in key areas,henced highly trained and motivated.Also were given the best equipment if possible,same as the SS.
