General Details
Name: Anti-Penetrative Ablation
Type (Category): Armor (Core)
Reference: Interstellar Operations: Alternate Eras (p. 80)
Description:
Often shortened to “ablative” armor (despite not at all resembling the anti-laser personal armor that uses the same term), anti-penetrative ablation armor is specifically designed to thwart the effects of armor-penetrating munitions and tandem-charge missiles. This is accomplished by enhancing otherwise-standard armor plates with additional layers of ribbed or perforated steel. This feature warps incoming penetrator rounds and explosives before they even reach the internal structure, but does nothing against lasers, particle weapons or raw kinetic rounds. This armor has seen limited deployment, mainly because its added weight barely offsets its benefits against special munitions.
Game Rules:
As long as the location struck still has at least 1 point of armor remaining, ABA Armor applies an additional –2 roll modifier to the critical hit check for all attacks made by weapons with armor-piercing abilities, including armor-piercing autocannon ammo, armor-piercing mortars, tandem-charge missiles, and tasers of all kinds. This modifier also applies to the special armor-defeating critical checks made for a hit location roll of 2 (whether or not the Floating Critical rule is in play). In all other respects, ABA armor functions as normal. Critical hits to ABA armor slots have no effect.

The special unit abilities described here are intended for use with the Alpha Strike rule system:
Anti-Penetrative Ablation Armor (ABA)
A unit protected by anti-penetrative ablation armor—often simply called ablative armor—is resistant to specialty munitions designed to pierce most other armor types. A unit with this special ignores attacks by taser weapons (MTAS and BTAS specials), and negates the bonus critical hit check made for attacks that use armor-penetrating ammunition and tandem-charge missile munitions.
