What was the primary responsibility of Security Police during Operation JUST CAUSE in December 1989?

The primary responsibility of Security Police during Operation JUST CAUSE was to secure landing strips. This mission involved ensuring the safety and operational capability of airfields that were critical for the movement of troops and supplies into Panama. By securing these landing zones, Security Police played a vital role in facilitating the overall military operation, allowing for efficient logistics and support for ground forces.

Securing landing strips was crucial for maintaining the flow of personnel and equipment into the area of operations, which was essential for the success of the military campaign. This task required a keen understanding of security protocols and the ability to respond swiftly to any potential threats.

The other options, while they might seem relevant within a military context, did not focus on the specific duties of Security Police. Commanding the military base, conducting air strikes, and training local police forces are functions typically aligned with other military and operational units rather than the responsibilities of Security Police during this particular operation.
