What does combat power primarily consist of in a military context?

Combat power in a military context refers to the capability of a military force to deliver effective force against an adversary, which encompasses a broad range of elements. The correct choice identifies that combat power is a multifaceted concept that includes weapons and technology, personnel and resources, as well as strategy and planning.

Weapons and technology are critical components as they provide the means to engage in combat and can greatly enhance a unit's effectiveness through advanced capabilities. Personnel and resources are equally essential, as the soldiers themselves are the ones who operate the technology and execute the strategies, while resources ensure that the forces are sustainment-ready.

Strategy and planning are vital for the successful application of combat power, allowing forces to effectively coordinate their efforts, exploit the enemy's weaknesses, and allocate their resources judiciously in a way that maximizes operational effectiveness.

Thus, since all these elements are integral to defining and achieving combat power in military operations, the choice indicating all of the above is accurate in encapsulating the complexity of what constitutes combat power.
