That 15 shermans, scores of personnel carriers, a few AT guns plus supporting infantrymen. Battalion minor? Even with the formidable 88 high velocity gun, it take some skill to destroy so many targets before even one Sherman to get within killing range of the 75mm or hit it from the side or rear. Surely there must be some piat teams who should get close enough to blow the tiger tracks to disable it.
I was a “panzergrenadier” first before being a BX 25mm gunner. It is possible to get close to a solitary tank that is unsupported by infantry without being spotted. Done it many time during NSF period. Being used to armour vehicles, AI learned to respect their capabilities but we are not afraid of it.
