Which tactic uses control lines and large water streams from fixed water supplies?

Explanation:
Anchoring and holding a line means establishing a solid anchor point on the defense and then using large water streams from fixed water supplies to keep the fire from breaching that line. The anchor provides a stable, defendable reference, while the heavy water application from fixed sources—like hydrants, ponds, or tanks—sustains cooling and direct suppression along the line, knocking down flames and preventing embers from crossing. This approach relies on reliable water availability to maintain a continuous, protective barrier rather than advancing or patrolling. The other tactics focus on movement, linking lines, or reconnaissance, not on holding a line with sustained large-stream water support.
