OK, this is just wrong (which, translated to English means, "I now want one"):
Ferromantic Invulnerability: The hull of the Achilles has been specially
constructed to resist even the most determined assault and is almost
preternaturally resilient. As a result, the Land Raider Achilles is not
subject to the particular effects of the Lance and Melta special rules
by attacks made against it. In addition it reduces the effects of all rolls
on the damage chart made against it (other than by Destroyer type
weaponry), by -1.
