To render enemy personnel incapable of interfering with an operation is to what?

The term that accurately describes the action of rendering enemy personnel incapable of interfering with an operation is "Neutralize." This action involves taking steps to diminish or eliminate an adversary's ability to conduct operations effectively. In a military context, neutralization can involve various tactics, such as defeating enemy forces through direct combat, suppressing their capabilities with firepower, or targeting their command and control structures. The focus of neutralization is to ensure that the enemy cannot pose a threat to your operational objectives.

Other terms like that of "Fix" generally imply holding enemy forces in place, which is more about preventing their movement rather than rendering them incapable of interfering. "Retain" is not typically used in this context, as it refers more broadly to maintaining control over an area or asset rather than directly affecting enemy capabilities. "Interdict," while related to limiting enemy movements or supply lines, does not specifically capture the essence of incapacitating enemy personnel. Thus, "Neutralize" is the most fitting choice for describing the intent to incapacitate the enemy effectively.
