The protection of military personnel on the battlefield has evolved far beyond basic ballistic testing. Today, the U.S. Army uses advanced modeling and simulation tools to optimize body armor systems for maximum survivability. One of the key technologies driving this effort is the MUVES-S2 survivability analysis system, now integrated with ORCA (Operational Requirement-based Casualty Assessment) to deliver more precise injury and survivability predictions.
A Modern Approach to Body Armor Survivability Testing
Body armor is no longer judged solely on whether it can stop a bullet. The Army’s comprehensive analysis includes how armor fits, how it interacts with other gear, its weight, mobility, comfort, and even the ability to quickly remove it in emergencies.
Through the use of MUVES-S2 and ORCA, analysts can now:
-
Model realistic battlefield threats.
-
Simulate impacts on various body armor configurations.
-
Predict injury severity using the Abbreviated Injury Scale (AIS).
-
Quantify differences between armor systems in terms of protection, weight, and coverage.
The Five-Step Body Armor Evaluation Process
The Army’s process for analyzing body armor survivability follows a structured five-step method:
-
Measure System Fit: Detailed measurements ensure the armor properly covers critical areas without restricting movement. Fit tests are conducted on both mannequins and real soldiers.
-
Create 3D Geometries: Advanced CAD modeling and laser scanning produce highly accurate digital models of the body armor and human anatomy.
-
Characterize Ballistic Protection: Extensive ballistic testing measures how well the armor protects against direct and indirect fire threats, using both V50 and V0 ballistic limits.
-
Identify Unique Vulnerabilities: Special attention is given to edge vulnerabilities where armor may fail, such as the edges of plates that can allow dangerous projectile fragments to reach the body.
-
Model Effectiveness: Using ORCA’s injury prediction capabilities, the Army evaluates how well armor protects against life-threatening injuries, focusing on serious injuries (AIS 3 or higher).
How the Shoot, Move, Communicate Imperative is Integrated in Body Armor Survivability
1. Shoot: Maintaining Combat Effectiveness
-
Weapon Handling & Accuracy: Body armor should not restrict shoulder movement, aiming stance, or trigger control.
-
Ballistic Protection: Armor must protect vital areas without sacrificing the ability to return fire quickly and accurately.
-
Survivability vs. Lethality Balance: The system must protect the warfighter while allowing them to stay lethal.
Body armor survivability models consider the soldier’s ability to continue combat operations after sustaining non-lethal injuries and whether the armor impedes weapon manipulation.
2. Move: Preserving Maneuverability
-
Mobility & Agility: Body armor design must balance weight with flexibility to ensure soldiers can sprint, crouch, climb, and take cover efficiently.
-
System Weight Distribution: Survivability analysis includes weight assessments to minimize fatigue and maximize range of motion.
-
Vehicle Ingress/Egress: Quick and unobstructed entry/exit from vehicles is essential for mission success and personal safety.
The evaluation process explicitly tests how the armor impacts the ability to perform rapid movements, tactical maneuvers, and complex battlefield tasks.
3. Communicate: Ensuring Connectivity and Situational Awareness
-
Gear Integration: Body armor must accommodate radios, headsets, antennas, and other communication devices without interference.
-
Situational Awareness: The fit and bulk of armor should not obstruct the soldier's peripheral vision, hearing, or ability to operate communication systems effectively.
-
Emergency Signals & Doffing: The design should allow quick donning and doffing for medical evacuation or signaling distress without hindering communication.
Survivability models assess how armor affects the positioning and accessibility of communication equipment in both operational and emergency scenarios.
A body armor system that only focuses on ballistic protection but limits the warfighter’s ability to shoot accurately, move effectively, or communicate reliably is ultimately a liability on the battlefield. The Army’s survivability analysis process ensures all aspects of the Shoot, Move, Communicate imperative are preserved and optimized, supporting the warfighter’s operational dominance and survivability.
