Modern battlefield architectures rely on the seamless integration of sensors, communication, energy supply and weapon systems. Each subsystem must exchange power and data reliably – under harsh environmental and mechanical conditions.
Key technical requirements include:
Personal soldier equipment forms a highly integrated system of systems. Despite growing wireless capabilities, wired connectivity remains essential for reliability, electromagnetic protection and energy efficiency.
| Subsystem | Role in the soldier system | Wired requirement | Typical interfaces & standards |
|---|---|---|---|
| Helmet-mounted optronics / AR | Reconnaissance, situational awareness | Power, video, control data | USB 3.x, HDMI, LVDS |
| Headset | Voice communication, hearing protection | Power, audio/control | MIL‑DTL‑55116 |
| Radio / communication module | Voice and data networking | Power, data | STANAG 4695, Nett Warrior 6‑pin |
| End User Device | Data processing and control | Power, USB, Ethernet, video | STANAG 4754, MIL‑DTL‑38999 |
| Battery pack | Central energy source | Power, control data | STANAG 4695, STANREC 4851 |
| Weapon system | Target acquisition, fire control | Power, data, optional video | MIL‑DTL‑32689, MIL‑DTL‑38999 |
Connectors and cables operate under permanent stress:
At the same time, increasing digitization demands higher bandwidth, secure transmission and combined power‑and‑data links in compact form factors.
To manage complexity and ensure interoperability, armed forces rely on defined interface standards. These standards reduce logistical effort, enable multi‑vendor systems and support long‑term platform strategies.
A key element is STANAG 4695, which specifies mechanical and electrical characteristics for soldier system power interfaces. It defines voltage levels, pin assignments and connector geometries – allowing batteries, radios, computers and PDUs from different origins to work together without adaptation.
Additional recommendations such as STANREC 4845 and STANREC 4851 further structure standardized data and energy paths within soldier architectures.
On the industrial side, connector systems such as the ODU AMC® NP series are designed to align closely with military standards and operational requirements.
Key characteristics include:
Typical applications include battery packs, PDUs, conformal wearable batteries (CWBs) and C4ISR peripherals.
While STANAG‑compliant connectors form the backbone of interoperable power supply, miniaturized high‑density connectors unlock additional optimization potential in closed subsystems.
The ODU AMC® High‑Density series is particularly suited for exposed equipment such as helmet systems or portable optics.

Future soldier systems depend on consistent networking, miniaturization and partial standardization. Hybrid connector technologies become strategic enablers for bidirectional data exchange and real‑time integration into multi‑domain operations.
Connectivity is no longer just an interface. It defines interoperability, usability and system growth across the entire lifecycle.
Those who control the interface shape the battlefield architecture of tomorrow.
