Attach is the placement of units or personnel in an organization where such placement is ____ _____.

The phrase “generally fixed” highlights the idea that personnel or units are placed within an organization with little expectation of change, reflecting stability. However, "relatively permanent" conveys a more nuanced understanding that while the placement is designed to endure, there may still be exceptions based on operational requirements or organizational changes.

In a military context, units and personnel are often assigned to specific roles and locations that they are expected to hold for extended periods, though this is not absolute. The terminology used aligns well with standard organizational practices where assignments remain in place to maintain consistency and effectiveness, allowing for clear lines of authority and responsibility. This reflects the ongoing need for strategic planning within an organization, recognizing that while placements are intended to be long-lasting, they can evolve based on mission needs or force structure adjustments.

Given the context, the choice “Table of organization (MTOE)” refers more to the organizational framework rather than the nature of personnel placement. Generally, “relatively temporary” denotes an expectation of short-term assignments, which does not match the context of the question that implies a longer commitment. Therefore, the emphasis on enduring assignment helps establish the landscape of the military organization’s approach to personnel placement.
