In the context of army aviation operations, characterized by high dynamism, intense confrontation, and the need for multi-domain collaboration, traditional radio frequency (RF) communication faces significant challenges such as spectrum congestion and inadequate anti-jamming capabilities. Wireless Optical Communication (WOC), distinguished by its ultra-high data transmission rates, low probability of intercept (LPI), and robust resistance to electromagnetic interference, has emerged as a pivotal technological solution to address these limitations. This paper presents a comprehensive overview of the key technological advancements in WOC for army aviation battlefields, analyzes the challenges encountered in complex operational environments, proposes systematic solutions aligned with military requirements, and explores its role in driving the transformation of future army aviation operational systems. The study highlights that through technological adaptation and system-level integration, WOC is evolving from a supplementary communication means to a core component, providing essential support for establishing resilient, covert, and high-speed communication networks for army aviation forces.
