Testing and Evaluation of Agentic AI Systems In Military Command and Control

Abstract
Agentic AI systems are being procured for military command and control (C2) under public commitments to rigorous testing and human oversight. Whether such commitments can be discharged depends on their supporting assurance case, which requires three elements: claims specifying the conditions for acceptability, evidence bearing on those claims, and an argument connecting the two. Through a structured review of 240 documented Testing and Evaluation (T&E) practices, spanning eight evaluation dimensions and three lifecycle stages, we identify eight assumptions that established methods make about their test article, grouped into four clusters: system specifiability, stability, composability, and supervisability. Agentic properties weaken all eight assumptions. This erosion affects the argument connecting evidence to claims, not the claims or evidence themselves. As a result, test results may satisfy process requirements, but they do not warrant the inference from tested to fielded behavior. We derive ten assurance claims for the first three assumption clusters and assess whether current and emerging methods can address each, mapping operational consequences through five C2 scenarios. Supervisability is identified but not assessed here, since evidencing it depends on system stability results and human factors T&E methods beyond the present scope. The documented record does not support broad claims about system-level behavior, but narrower claims remain recoverable in principle, contingent on mature methods: bounded mission envelopes, trajectory-grounded correctness, executable runtime constraints, and characterized run-to-run variance. Part of the evidentiary burden shifts into deployment, making the determination to field a continuing act. Where evidence cannot be generated, the residual uncertainty can be governed through defined expiry conditions and assigned ownership.
Figures & tables
| Finding | Implication | Where addressed |
| Established T&E methods rest on assumptions about specifiability, stability, composability, and supervisability that agentic systems weaken by design. | Test evidence can satisfy process requirements while the inference to fielded behavior remains insufficient; the connecting argument needs direct scrutiny. | §4 |
| Assurance claims are recoverable in a narrower form. | An assurance case decomposed into narrow claims with declared residual uncertainty can be supported by the documented record, whereas a broad system-level claim cannot. | §5.1-5.3 |
| Some evidence can only be generated in service. | The determination to field becomes a continuing act under governance that time-bounds the validity of evidence. | §5.2 |
| Faculties | Definition | Related terms in the literature |
| Autonomy | The system operates without direct human intervention and controls its own actions and internal state. | Independent execution ( Shavit et al., 2024 ) ; directness of impact ( Chan et al., 2023 ; Kraprayoon et al., 2025 ) ; degree of user supervision ( Kapoor et al., 2024 ) |
| Reactivity | The system perceives its environment and responds to changes within it, including novel or unanticipated circumstances. | Adaptability ( Shavit et al., 2024 ; Kraprayoon et al., 2025 ) ; environments subject to unexpected change ( Kapoor et al., 2024 ) |
| Pro-activeness | The system takes the initiative to pursue an objective rather than acting only in response to its environment. An operator supplies the objective without a specification of how it is to be accomplished, and the objective may be complex or extend over a long horizon. | Underspecification and goal-directedness ( Chan et al., 2023 ) ; goal complexity ( Shavit et al., 2024 ) ; pursuit of goals without instruction on how to pursue them ( Kapoor et al., 2024 ) |
| Social ability | The system communicates with humans and other systems using a formal language, allocates tasks among additional instances of itself, and functions in environments with multiple stakeholders. | Multi-agent collaboration, including delegation to subagents ( Kraprayoon et al., 2025 ) ; collaboration ( Rickli and Knappe, 2026 ) ; others treat multiple stakeholders as an attribute of the environment ( Kapoor et al., 2024 ; Shavit et al., 2024 ) |
| # | Property | Description | Function | Component |
| P1 | Persistent memory | The system preserves contextual information across sessions and operator transitions. As a result, a previously characterized instance may differ from its later operational state. | Learn | Memory and data |
| P2 | Objective flexibility | The system adjusts its priorities in response to contextual changes without explicit instructions. New goals may diverge from the initially assigned objectives. | Decide | Model; orchestrator |
| P3 | Expanding integration 5 5 5 Expanding integration refers to growth in the set of platforms, tools, and subagents the system can invoke, not to capability as such. Its consequences include a larger reachable action space, which compounds the open-ended action problem in P4, a wider vulnerability surface, and a broader boundary for testing to characterize. | The system functions across an expanding set of platforms, databases, and tools, and this set can grow beyond its certified configuration after deployment. | Act | Tools |
| P4 | Open-ended action space | New actions arise from goal-directed reasoning and cannot be exhaustively specified during design. Authorization boundaries frequently remain ambiguous when high-level goals are delegated. | Decide, Act | Orchestrator; tools; operator interface |
| P5 | Proactive information seeking | The system independently determines which sources to query, thereby shaping its own information environment. | Sense | Tools, memory, and data |
| P6 | Accumulated non-determinism | As each step informs the next, variance accumulates along the trajectory rather than remaining independent across steps. At operational chain lengths, outputs may differ substantially even from identical initial inputs, so that a reproducible test case yields a distribution of trajectories rather than a single expected result. | All, iterated | The loop from model through tools and memory and back |
