what is even worse for tanks is just what was considered a "loss". The US in NW Europe didn't consider a tank a "loss" unless it suffered catastrophic damage or burned. A large fire ruined the heat treatment of the armor making it rather questionable. Many a "knocked out" tank had the crew's bodies removed, the inside cleaned, equipment repaired and shot holes plugged and welded and returned to service. Some tanks were back in service in just a few days.
