Which CAB has more robust fire power capability?

The option indicating "Heavy" is the correct answer because a Heavy Combat Aviation Brigade (CAB) is designed to provide significantly greater firepower compared to the other types of CABs. Heavy CABs typically operate utilizing a larger fleet of attack helicopters, such as the AH-64 Apache, and ground support systems that enhance their operational capabilities. This setup allows them to engage in more intense fire support missions and help ground forces with concentrated firepower during combat operations.

In contrast, Light and Medium CABs have more limited capabilities in terms of firepower due to their operational focus on mobility and flexibility. Light CABs tend to use platforms designed for rapid deployment and ease of transport, often at the expense of heavier armament. Medium CABs have a more balanced approach but generally don’t possess the same level of heavy fire support as the Heavy CAB. The term "Combat Ready" does not specify a type of brigade and does not inherently signify an increase in firepower capability. Instead, it refers to the operational readiness of a unit, which can vary across all the types of CABs listed. Thus, Heavy CABs are the ones best suited for scenarios requiring robust firepower.
