In the United States, two military standards govern the use of combat net radios and the host applications that communicate over the network:
MIL-STD-188-220 and MIL-STD-2045-47001. In addition to IETF RFCs governing UDP, TCP, and IPv4/IPv6, all seven layers of the
OSI communications architecture are addressed. MIL-STD-2045-47001 covers layer 7 (
