Secondo quanto riportato su wikipedia le caratteristiche delle armi autoforgianti (esistono anche le mine) sono compatibili con quelle dell'attacco escluso il fatto che essendo armi anticarri un mezzo così piccola avrebbe comunque dovuto subire danni ben piú gravi.
Some anti-armor weapons incorporate a variant on the shaped charge concept that, depending on the source, can be called a Self Forging Fragment (SFF), Explosively Formed Projectile (EFP), SElf FOrging Projectile (SEFOP), plate charge, or Misznay Schardin (MS) charge. This warhead type uses the interaction of the detonation wave(s), and to a lesser extent the propulsive effect of the detonation products, to deform a dish/plate of metal (iron, tantalum, etc) into a slug shaped projectile of low length to diameter ratio (L to D) and project this towards the target at around two kilometres per second. The SFF is relatively unaffected by first generation reactive armor, it can also travel up to, and above 1000 cone diameters (CDs) before its velocity becomes ineffective at penetrating armor due to aerodynamic drag, or hitting the target becomes a problem. The impact of a SFF normally causes a large diameter, but relatively shallow hole (in comparison to a shaped charge) of, at best, a few CDs. If the SFF perforates the armor, extensive behind armor damage (BAD), also called behind armor effect (BAE) occurs. The BAD is mainly caused by the high temperature and velocity armor and slug fragments being injected into the interior space and also overpressure (blast) caused by the impact. More modern SFF warhead versions, through the use of advanced initiation modes, can also produce rods (stretched slugs), multi-slugs and finned projectiles, and this in addition to the standard short L to D ratio projectile. The stretched slugs able to penetrate a much greater depth of armor, at some loss to BAD, multi-slugs are better at defeating light and/or area targets and the finned projectiles have greatly enhanced accuracy. The use of this warhead type is mainly restricted to lightly armored areas of MBTs (Main Battle Tanks), the top, belly and rear armored areas for example. Its use in the attack of other less heavily armored AFVs (armored fighting vehicles) and in the breaching of material targets (buildings, bunkers, bridge supports, etc), it is well suited. The newer rod projectiles may be effective against the more heavily armored areas of MBTs. Weapons using the SEFOP principle have already been used in combat; the smart submunitions in the CBU-97 cluster bomb used by the US Air Force and US Navy in the 2003 Iraq war used this principle, and the US Army is reportedly experimenting with precision-guided artillery shells under Project SADARM (Seek And Destroy ARMor). There are also various other projectile (BONUS, DM 642) and rocket submunitions (Motiv-3M, DM 642) and mines (MIFF, TMRP-6) that use SFF principle.
