What Is 118th Air Support Operations Squadron

Overview

The 118th Air Support Operations Squadron (118 ASOS) is a specialized unit within the Tennessee Air National Guard, assigned to the 118th Wing at Joint Base Berry Field in Nashville, Tennessee. As a component of the Air National Guard, the 118 ASOS operates under both state and federal authority, enabling it to respond to domestic emergencies and deploy overseas during national defense operations. The unit’s primary mission is to provide tactical command and control of airpower in direct support of ground forces, particularly through the coordination of close air support (CAS) missions.

Established in 1998, the 118 ASOS evolved from earlier air support units with roots in World War II-era operations. Its formation was part of a broader restructuring within the Air National Guard to enhance joint warfare capabilities, particularly in integrating air and ground combat operations. The squadron was developed to meet the growing need for precision air-ground coordination in modern warfare, where real-time communication and battlefield awareness are critical to mission success and force protection.

The significance of the 118 ASOS lies in its role as a force multiplier for U.S. and allied ground units. By embedding trained airmen with Army and Marine units, the squadron ensures that airpower can be rapidly and accurately directed against enemy targets. This capability has proven essential in conflicts such as Operation Enduring Freedom and Operation Iraqi Freedom, where precise airstrikes minimized collateral damage and maximized operational effectiveness. The unit continues to train rigorously to maintain readiness for both combat and humanitarian missions.

How It Works

The 118th Air Support Operations Squadron functions by deploying highly trained personnel to forward operating locations, where they integrate directly with ground combat units. These airmen, often Joint Terminal Attack Controllers (JTACs), are certified to communicate with pilots and coordinate airstrikes using secure radio and data links. The process involves identifying targets, deconflicting airspace, and ensuring that weapons delivery is both safe and effective. This requires split-second decision-making under pressure and a deep understanding of both air and ground tactics.

• Joint Terminal Attack Controller (JTAC): A certified operator trained to direct aircraft during close air support missions. JTACs undergo rigorous training and must maintain certification through regular evaluations.
• Terminal Control Party (TCP): Small teams of airmen deployed with ground units to provide real-time air support coordination. These teams are embedded at the battalion level or higher.
• Forward Air Controller (Airborne) – FAC(A): While not directly part of the 118 ASOS, this role complements their mission by providing airborne coordination of multiple aircraft in complex environments.
• Tactical Air Control Party (TACP): The broader organizational structure to which ASOS units belong. The 118 ASOS is a specialized element within the TACP mission set.
• Link 16 Data Network: A secure, digital communication system used to share real-time battlefield data between ground forces and aircraft, enhancing situational awareness.
• Combat Air Support (CAS) Integration: The 118 ASOS ensures that airpower is synchronized with ground maneuver plans, reducing the risk of fratricide and increasing mission success rates.

Key Details and Comparisons

The comparison above highlights the structure and distribution of Air Support Operations Squadrons across the United States. While each unit operates independently, they share a common mission framework under the Air National Guard and Air Combat Command. The 118th ASOS stands out due to its integration with the larger 118th Wing, which also includes intelligence, surveillance, and reconnaissance (ISR) assets. Unlike some ASOS units that are co-located with active-duty bases, the 118 ASOS operates from a National Guard-specific installation, emphasizing its dual state-federal role. These squadrons are critical in maintaining a scalable, responsive air support network that can be rapidly deployed during crises.

Real-World Examples

The 118th Air Support Operations Squadron has been actively involved in numerous military operations since its inception. During deployments to Afghanistan and Iraq, members of the unit embedded with U.S. Army and coalition forces to provide real-time air support coordination. In high-intensity combat zones, their ability to call in precision airstrikes on enemy positions significantly reduced friendly casualties and accelerated mission objectives. These operations often occurred in complex urban environments, where the margin for error was minimal, underscoring the importance of their training and expertise.

Domestically, the 118 ASOS has supported disaster response efforts, including coordination during hurricanes and large-scale emergencies. In such scenarios, they assist in establishing communication networks and coordinating aerial reconnaissance or supply drops. Their dual-use capability makes them a valuable asset not only in warfighting but also in homeland defense and civil support missions.

1. Supported Operation Enduring Freedom (Afghanistan, 2001–2021) with embedded JTACs
2. Provided air-ground coordination during Operation Iraqi Freedom (2003–2011)
3. Assisted in Hurricane Katrina relief efforts (2005) through command and control support
4. Conducted joint training exercises with the 101st Airborne Division at Fort Campbell

Why It Matters

The 118th Air Support Operations Squadron plays a crucial role in modern military operations by bridging the gap between air and ground forces. As warfare becomes increasingly joint and multidomain, the ability to rapidly integrate airpower into ground combat is essential for maintaining tactical superiority. The 118 ASOS ensures that U.S. and allied forces can leverage air assets safely and effectively, even in the most challenging environments.

• Impact: Reduces the risk of friendly fire by ensuring precise coordination between ground troops and aircraft.
• Force Multiplier: Enhances the combat effectiveness of ground units by enabling rapid access to airpower.
• Cost Efficiency: Leverages National Guard resources to maintain readiness without the full cost of active-duty units.
• Domestic Readiness: Provides critical support during natural disasters and civil emergencies.
• Global Deployability: Trained personnel can be deployed worldwide within hours when federalized.

In an era defined by asymmetric threats and rapid response requirements, units like the 118 ASOS are indispensable. Their expertise ensures that airpower is not only available but also applied with precision, speed, and coordination. As military doctrine continues to evolve, the role of tactical air control units will only grow in importance, solidifying the 118th Air Support Operations Squadron’s place in national defense.
