3 CP and 1 CD, assuming the CD is paired with one of the CPs, will net your squad -$30% × 1.15 + 30% + 30%$ to enemy armor.

Though if you want to be most effective against the Tri-dolons you should be using 2 CDs, not just 1 (-$30% × 1.15 + 30% × 1.15 + 30%$). This will get you closest to 100% armor reduction without actually reaching it.
