The mission of the 21st Theater Sustainment Command (TSC) is to execute mission command of operational sustainment across the European theater, ensuring the readiness and effectiveness of U.S. forces.
The 21st TSC, often referred to as "First in Support," plays a critical role in supporting U.S. Army and joint operations throughout Europe. Its comprehensive mission encompasses a wide array of logistical and support functions vital for maintaining operational capabilities and projecting power.
Core Responsibilities of the 21st TSC
The command's mission is multifaceted, focusing on various key aspects of theater sustainment. This includes providing essential services and strategic support that underpin military operations.
Operational Sustainment Across Europe
At its core, the 21st TSC executes mission command of operational sustainment across the European theater. This involves overseeing and coordinating all aspects of logistics, supply, maintenance, transportation, and human resources support for U.S. Army Europe and Africa (USAREUR-AF) units and operations. This extensive reach ensures that forces are well-equipped and supplied wherever they are deployed within the region.
Reception, Staging, Onward Movement, and Integration (RSOI)
A crucial component of its mission is conducting Reception, Staging, Onward movement, and Integration (RSOI). This process is vital for deploying forces, equipment, and supplies into a theater of operations.
- Reception: The initial arrival of personnel and materiel.
- Staging: Organizing and preparing these assets for onward movement.
- Onward Movement: Transporting them to their operational areas.
- Integration: Incorporating them into existing command and control structures and operations.
Setting the Atlantic Resolve Joint Operation Area
The 21st TSC is also responsible for setting the Atlantic Resolve joint operation area. Operation Atlantic Resolve is a demonstration of U.S. commitment to collective security in Europe, undertaken in response to Russian aggression in Ukraine. "Setting the area" involves establishing the necessary logistical infrastructure, support mechanisms, and operational environment for forces participating in this continuous, rotational presence across Europe.
Theater Opening, Distribution, and Sustainment
Furthermore, the 21st TSC executes theater opening, theater distribution, and theater sustainment in support of U.S. forces and operations.
- Theater Opening: Establishing and expanding logistics infrastructure at the outset of a mission or conflict, including ports, airfields, and supply depots.
- Theater Distribution: Managing the flow of supplies, equipment, and personnel across the entire theater to ensure they reach their intended destinations efficiently.
- Theater Sustainment: Providing continuous, long-term support for all classes of supply, maintenance, and services required to maintain combat power and readiness.
Key Operational Pillars
The mission of the 21st TSC relies on several interconnected operational pillars:
| Operational Pillar | Description |
|---|---|
| Mission Command | Directing and overseeing all sustainment operations in the European theater. |
| Logistics Management | Coordinating the supply chain, including procurement, storage, and delivery of essential resources. |
| Movement Control | Managing the strategic and tactical transportation of personnel and materiel via various modes (road, rail, air, sea). |
| Infrastructure Support | Developing and maintaining critical logistical infrastructure such as supply depots, maintenance facilities, and transportation hubs. |
| Human Resources | Providing personnel services, including casualty support, postal services, and human resources management. |
The Importance of Theater Sustainment
The ability of the 21st TSC to execute its mission directly impacts the readiness and effectiveness of U.S. forces in Europe. Without robust sustainment, operations would grind to a halt due to lack of supplies, maintenance issues, or insufficient personnel support. The command's efforts ensure:
- Continuous Operations: Forces can maintain their presence and execute missions without interruption.
- Rapid Deployment: New units and equipment can be quickly integrated into the theater.
- Enhanced Readiness: Soldiers have the necessary equipment, supplies, and support to be combat-ready.
- Strategic Flexibility: The U.S. can project power and respond to contingencies across the European continent.
