Final answer:
The CAB with more robust firepower capability has more powerful and advanced weapons systems for attacking enemy targets.
Step-by-step explanation:
The Comparative Assessment Battery (CAB) that has more robust firepower capability is the one with more powerful and advanced weapons systems for attacking enemy targets. These weapons systems are typically assessed based on factors such as range, accuracy, rate of fire, payload capacity, and versatility. Examples of CABs with strong firepower capabilities include the AH-64 Apache attack helicopter and the M1 Abrams main battle tank.
