As for western tanks I spend the last few months to make some research. The M1's that were completely burnt off and heavy damaged were victims of IED's and non extuinguished fuel fire, it is not uncommon with IED's. However dedicated anti tank weapons actually not made heavy damage, even ammunition cook off mostly occured only in one magazine while other ones stayed intact (yes, in M1 also bustle magazine is in fact two separated magazines). Everything depends on circumstances and what happened after attack.
I evena ctually compared Soviet made tanks and M1's attacked by dedicated (means no IED's or EFP's) anti tank weapons, even if vehicle was hit and disabled, M1's stayed mostly intact besides hit area, this also means rather powerfull ATGM warheads (AGM-114), while for example T-72B's used by Georgia hit in weakly protected areas mostly ended as completely destroyed hull without a turret.
