What does SACLOS stand for in military terminology?

SACLOS stands for Semi-automatic controlled line of sight. This terminology is crucial in military contexts, especially concerning guided missile systems. In a SACLOS system, the operator tracks the target visually and uses a control system that automatically adjusts the missile's guidance to keep it aimed at the target during flight. This approach allows for a more straightforward interface for the operator while still relying on their skill to maintain the line of sight.

The term emphasizes that while there is a degree of automation, the operator remains actively involved in aiming and tracking, which can enhance decision-making and responsiveness in dynamic combat situations. The other suggested options contain terms that do not accurately reflect the principles or operational characteristics of SACLOS, leading to confusion about how the system works in practice.
