Which terminology indicates that a missile has been defeated?

The correct term to indicate that a missile has been defeated is "Neutralized." This term is commonly used in military and defense contexts to describe a situation where a threat, such as a missile, has been rendered ineffective or incapacitated. Neutralization can occur through various means, including interception, destruction, or rendering the missile non-functional, ensuring it is no longer a threat.

The other options do not accurately convey the formal military terminology associated with counteracting missiles. "Trashed," while colloquially suggesting destruction, lacks the specificity and official recognition used in defense discussions. "Deflected" implies that the missile was redirected but does not necessarily indicate that it poses no further threat. "Disregarded" suggests that the missile is ignored, which does not convey any action taken to neutralize it. Therefore, "neutralized" is the most precise and appropriate language used in military terminology for indicating that a missile has indeed been defeated.
