What tactic is compromised by using pre-connected attack lines?

Using pre-connected attack lines primarily compromises the reverse lay tactic. In a reverse lay, the fire apparatus is positioned at the fire scene, and the hose is deployed back to the water source. This allows for the firefighters to fight the fire immediately while ensuring the hose is supplied from a distance. However, when pre-connected attack lines are used, the hose has already been deployed on the apparatus and is connected, which may inhibit the ability to lay additional hose lines back to the source while maintaining the same level of readiness for immediate firefighting.

With the use of pre-connected lines, firefighters are generally tied to the amount of hose that is pre-attached and may not be able to efficiently adapt to the layout of the scene or the water supply infrastructure around them. This can limit operational flexibility and potentially delay establishing a solid water supply strategy that could be achieved by a reverse lay. Additionally, firefighters may find themselves in situations where they need to deploy more hose than what is already pre-connected, complicating logistics and response efforts in critical situations.
