In defensive operations, what is considered initial defilade time?

Initial defilade time is a critical concept in defensive operations, referring to the period during which a crew has the opportunity to engage targets while being shielded from enemy observation or fire. The correct choice, which pertains to the crew locking onto all targets in the field, highlights the ability of the crew to prepare for engagement without being exposed to danger.

When the crew has all targets in the field locked, it indicates that they have identified potential threats and are ready to engage while taking advantage of cover. This preparation is essential in maximizing the effectiveness of defensive operations and minimizing risk during combat. It reflects a well-prepared and organized team that is able to strategically position themselves against enemy advances.

The other choices do not accurately describe initial defilade time. For instance, if the crew is not properly positioned, they will likely be vulnerable and unable to take full advantage of defensive tactics. Engaging all targets implies active engagement rather than the preparatory period that initial defilade time represents. Lastly, the action of being disengaged suggests a lack of readiness, which is contrary to the intent of maximizing the initial defilade time when the crew should be fully engaged and prepared to act.
