The scenario requires you to use a CC Weapon with the Anti-materiel Trait, so D-Charges have to be used in CC Mode.
QK can use YuanYuan DA-CC-Weapon loadout (9pts) to destroy the AC. PH13 gives you at least a 25% chance per Armorsave to chip away some STR and you do not have to cross the whole table to get to the AC. Though it never worked yesterday while using YY with my Ikari Force against Vanilla CA due to mistakes in deployment on my side...
you are right - sorry for my misquote. That's a 30% chance then - but it didn't help me either in my game :)
