Regarding Armor-Piercing Ammo and TacOps "Advanced Determining Critical Hits" (TO pp. 74-75): How do these two rule sets interact? Does 'Determining Critical Hits' stack with AP ammo for Auto Cannons? It feels like the AC/20 gets a tremendous boost, while the AC/2 becomes absolutely useless.

AC/20
TACTICAL  OPS: AC/20 needs a 6+ (Needs 9+ with -4 bonus from the 'Determining...' rule and +1 penalty from the AP ammo)
TOTAL WARFARE: AC/20 needs a 9+ (Needs 8+ with +1 penalty).

AC/2
TACTICAL  OPS: AC/2 needs a 13 (Needs 9+ with +0 bonus from the 'Determining...' rule and +4 penalty from the AP ammo)
TOTAL WARFARE: AC/2 needs a 12 (Needs 8+ with +4 penalty).

You're conflating two different sets of rules.  The Advanced Determining Critical Hits rules in TacOps apply to normal critical hit rolls which are made when the internal structure of a unit takes damage.  Armour-piercing autocannon ammunition causes a separate, unique opportunity for a critical hit against a still-armoured location.  The modifier to that special critical hit roll is not applied to attacks that deal damage to the target's IS or normal hit-location table through-armour criticals, regardless of whether or not the standard Total Warfare or advanced TacOps critical hit rules are in use.

Awesome!! That's exactly what I needed. :)
