What distinguishes personal effects that need to be shipped due to security concerns?

The correct answer highlights that personal effects are distinguished by the lack of adequate space and security, which necessitates their shipment. In situations where personnel are departing, there could be a variety of items they possess that may not have a secure place for storage onboard. This could be due to space limitations in terms of available storage or the need to maintain a secure environment while personnel are transitioning, especially in sensitive or military operations.

Shipping these personal effects ensures they are safeguarded and properly managed outside the immediate environment, reducing the risk of loss or unauthorized access. This is particularly relevant in logistics and military settings where security and space considerations are paramount.

While items that are too valuable or excessively heavy could indicate a need for shipping, the determining factor in this context is security and available space. Additionally, the fact that the personal effects belong to departing personnel is not inherently a reason for shipping them; it is the conditions surrounding their storage and handling that compel shipment.
