Which LASER application is NOT in use for military operations?

The correct answer is that medical research is not a LASER application typically used for military operations. While the military does utilize LASER technology extensively for various applications, including range finding, target designation, and communication, the medical research application is generally associated with civilian sectors rather than military ones.

In military contexts, a range finder helps determine distances to targets, allowing for precise artillery or missile targeting. Target designators utilize LASERs to illuminate targets for guided munitions, enhancing strike accuracy. Communications via LASER technology can also play a role in secure data transmission in tactical environments. In contrast, medical research using LASER techniques, while important, does not have a direct military application and is more focused on health and medical advancements, which are typically outside the scope of military operations.
