Define 'combined arms' as described in MCDP 1.

'Combined arms' refers to the integration of various combat capabilities into one force, which is a key principle in MCDP 1. This concept emphasizes leveraging the strengths of multiple military elements—such as infantry, armor, artillery, and aviation—working together in a cohesive manner to achieve a common objective. By employing different combat capabilities, forces can complement each other and effectively overcome the weaknesses of one component with the strengths of another.

This integrated approach allows for more flexible and adaptive responses to combat situations, enhancing overall effectiveness on the battlefield. The synergy created by combined arms ensures that units can execute complex operations more efficiently, providing a decisive advantage against the enemy. The focus is not just on the individual components, but rather on how they can work together in a harmonized effort to maximize their collective impact.

In contrast, other options do not fully encapsulate the essence of 'combined arms' as described in MCDP 1. The collaboration between different military branches, while important, lacks the depth of integration specified in the correct choice. Similarly, dividing military operations into specialized units or focusing solely on technology misses the broader strategy of how different combat capabilities are intended to operate in conjunction to achieve greater effectiveness.
