Which security halt allows for an expedient transition between holding and moving?

The short security halt is specifically designed to allow for an expedient transition between holding and moving. During this type of halt, units can quickly assess their surroundings and resume movement as necessary, making it ideal for maintaining the momentum of an operation while ensuring security.

In contrast, the listening halt focuses more on gathering intelligence through sound and is typically longer, which can slow down the overall pace of movement. The long security halt is meant for extended pauses where more information gathering or tactical planning can take place, making it less conducive to quick transitions. The emergency halt is implemented in urgent situations where immediate cessation of movement is required, which does not support a smooth shift back to movement afterwards.

Thus, the short security halt serves as a balance, providing adequate security while allowing units to maintain their operational tempo effectively.
