What is another method, besides Direct Alignment, used to engage targets without an FDC?

Direct Lay is another method used to engage targets without the assistance of a Fire Direction Center (FDC). This technique allows gunners to fire directly at the target while using visual observation. It involves the forward observer or gunner aiming the mortar at a target that can be visually identified and manually adjusting the aim based on observed impacts.

This method provides a way to respond quickly to enemy threats or to engage targets in close proximity, where traditional communication and coordination with an FDC might not be practical or timely. The shooter can make real-time adjustments to aim based on immediate visual feedback, making it effective for fast-paced scenarios.

Other methods such as Indirect Lay and Combat Lay can involve more complex steps and usually require some form of computed or coordinated support. Indirect Lay, for example, typically relies on predetermined firing data and might involve more complex calculations or guidance from an FDC. Combat Lay usually implies a more tactical approach in a combat environment, often under fire, which might not fit the context of engaging a visible target without FDC support. Precision Lay would focus on accuracy and precision that could demand additional repetitive adjustments or coordination, which is not the core advantage of Direct Lay.
