Soldier systems use HUDs and HMDs for real-time tactical information. UAVs depend on display screens for flight control and data management. Training simulators with high-fidelity screens aid in mission rehearsal and marksmanship training. In naval operations, display screens are essential for navigation, communication, and weapon systems operation. 

 LCD screens are essential in communication systems for secure military communication, supporting the exchange of vital information. They also have a crucial role in medical applications, aiding medical imaging, patient data management, and surgical guidance in field hospitals. 

Overall, the widespread use of LCD displays in the military underscores their significance in achieving operational objectives, ensuring situational awareness, and enhancing the safety of military personnel. They provide real-time data, visual support, and communication capabilities that are integral to military mission success and modern strategy.
