In recent years, ARL has developed the ability to perform needed biological experimentation using various physiological and cadaveric models. In parallel with the near- and midterm development of analysis tools using these models, ARL continues to refine simple physical models such as efforts to replace existing plywood dummies with more anthropomorphic and physically responding manikins. Both are indispensable, but both need to be further developed and validated in several areas over a near-term to long-term time frame.
For MUVES, validation and extension efforts are clear and critical; no other organization will develop a robust analysis tool central to the ARL mission.
For ORCA, although long-needed efforts have begun to improve basic aspects of components of the framework, principally increasing resolution for the ComputerMan component, planning and core funding for additional improvements and validation are urgently needed.
The scope of these tools for Army development and planning is so broad that development needs to occur on a deliberate and well-funded basis.
The challenge is to develop an organic plan for long-term development of both tools that incorporates current threats and addresses risk assessments for threats to personnel in the intermediate and long term. Desirable developments include increases in computational efficiency, especially for parallel use.
Some of this development has started. In addition, the provision for closer and more organic integration of the individual tools within ORCA would be highly desirable. It would also be extremely valuable to add BABT capabilities for personal protective equipment PPE , particularly helmet and thoracic body armor. It is essential that ARL provide consistent long-term planning and funding for this effort.
However, substantial challenges impede the most efficient use of this data. This is an essential limitation or domain conflict , since effective personnel risk assessments cannot be performed without granular knowledge of injuries well beyond AIS coding categories. Indeed, such detailed medical information offers the opportunity to inform and develop more effective risk models based on battlefield functional capacity, rather than simple risk of injury or fatality reflected in the AIS scores alone.
In this system, injuries are ranked using an ordinal scale from 1 minor injuries to 6 maximum. This scaling, developed principally as a threat to life scale in the automobile biomedical community, has been extended to military injuries.
For example, a survivable midshaft femur fracture AIS 3 may be as militarily significant as a likely fatal injury from an aortic laceration AIS 5 , depending on the needed functional capacity for the mission. For future efforts, it is important to both collect and assess injury data with higher granularity and with an eye toward the use of military injury data as an assessment of the mission- oriented functional capacity on the battlefield.
Higher degree of automation
One long-standing challenge is in the development of models for BABT, especially for the head and torso. This development includes the refinement or replacement of existing physical models for ballistic BABT with various fragments and ballistic threats. This subject has been addressed by several previous National Academies studies, and the essential recommendations have not been addressed even after the passage of a number of years.
These previous National Academies studies emphasize the limitations of both the physical models and the underlying injury biomechanics.
Vehicle body engineering
As noted earlier, laudable investigations of helmet BABT in physiological models has begun, but the development of such models and physical surrogates has been needed from the beginning of the development of aramid composites for ballistic helmets in the s and the development of hard body armor in the s.
Owing to the importance of such models to the Army, addressing this challenge needs to take a central position in the development of personal vulnerability models. It is important for these models to include a plausible set of injury assessments with various battlefield functional capacities and universal joint tasks, not just lethality and severe incapacitation models.
For computational models, the challenge of improving finite element models can be addressed, in part, by attempting to add models that contractors develop for military programs, paid for by the Army, to the mix of available tools for the broad development of useful BABT injury risk models.
For field epidemiology, collaborations with Program Executive Office Soldier, MRMC, the Armed Forces Medical Examiner, the intelligence community, operational commands, and others need to be formalized to obtain as much information from existing personal protection, including vehicles and armor to assist in developing and validating risk models. For example, the PPE needs to be sent back to ARL from the theater both in instances where it has worked successfully and in instances where the soldier has sustained injury in spite of or because of the PPE.
For instance, threats have a distribution of energies and effects. Human anthropometry arises in military operations as a distribution.
Even material properties of constituents of vehicles, protective equipment, and people are a distribution. The challenge of using appropriate statistics in assessments is twofold. Often the distribution needed for a given analysis is unknown and is not feasible to measure or obtain. Therefore, approximations need to be made to make the assessment tractable. The other major challenge is determining the appropriate analysis for significance. If the variance of a particular measurement is small, even unimportant differences can be statistically significant.
When assessing the significance of an effect, it is important to consider not only the statistical significance but also the size of the effect and whether a difference is a clinically or programmatically meaningful difference. Evolution of this philosophy continues in the biomedical field to emphasize important differences in treatments, not simply differences with a statistically discernable mean.
There appears to be insufficient core funding to advance key areas in BABT risk modeling, and the existing efforts appear to be currently funded on a somewhat ad hoc basis. This has led to early design improvements and has avoided costly redesigns later in the development cycle. Following pre-Milestone B applications, these models have been provided to system development contractors to continue iterative HSI analysis as system concepts and designs continued to evolve.
The HSI team also developed a much-needed Manpower Requirements Criteria MARC toolset that enables designers to trade off candidate designs to cost-effectively optimize soldier accommodation.
The ARL Human Research and Engineering Directorate HRED has recruited and hired early-career scientists and engineers and is mentoring them to fill in for more experienced personnel who will be retiring in the near future. There has been much work, over many years, to improve and extend the capabilities of the digital human models and the accompanying soldier clothing and equipment models.
This has allowed comprehensive static evaluation analysis and assessment of male and female soldier accommodation in ground combat vehicles and other systems. ARL supports contractors in the use of these models during design development to ensure their proper employment. The extension of modeling analysis techniques to include dynamic conditions is applauded, as it could significantly improve the ability to analyze vehicle safety.
IMPRINT has been employed by hundreds of contractors to assess system concepts, preliminary designs, baseline designs and to propose design changes. This has resulted in significant cost avoidance over many years. This tool has potential to assist contractors in assessing soldier interface characteristics and job demands against the capabilities of the personnel identified in the target audience description TAD for operational, maintenance, support, and training positions.
It then may also allow contractors to correct user interfaces, modify job or training requirements, or propose changes to personnel requirements prior to establishing the system baseline at the stage of preliminary design review PDR.
