I worked on the handheld JTRS radios some years ago, it was running Green Hills Integrity RTOS at the time.

Probably not Windows. These radios require a POSIX compliant OS. In the old ones (not the latest spec) the only allowed external calls were to CORBA services and POSIX capabilities. This was to aid portability (discussed in TFA: didn't help because changing capabilities usually required hardware and firmware changes, not just software).

Windows 2000 was just barely POSIX compliant for defense purposes.

Yeah what's up with that? It reads like a requirement written to be fulfilled by a specific vendor with an already identified offering.

CORBA was the rage back in the 1990s. CORBA, WebObjects, and COM all were part of the push to package services into “replaceable components” (like microservices today).
