What I meant was that the tanks break in general. However, I once had a smoker that melted inside a Pershing, I got a little curious when smoke started coming out of the engine grates on the rear deck. It nearly caught fire after melting, I caught it just in time to prevent the heat from melting the rear hull of the tank. That woulda required some fabrication to fix! Woulda been a good excuse to make an M46 out of it!
