I assume they are referring to: "a. Military, warfare, nuclear industries or applications, espionage, use for materials or activities that are subject to the International Traffic Arms Regulations (ITAR) maintained by the United States Department of State..." Since that's the only reference to "military" I can find. Regardless, if we assume that the US Dept of State does not list the US military on its prohibited list, this would not be an issue. Even if they do "prohibit" this elsewhere, it would not in fact prevent the US military from using it if they were able to say (to the satisfaction of a US judge) that they had a compelling national security reason to do so. And if all of that failed, and for some reason the US military wanted to use Llama2, they would just do it anyway, and neither FB nor the judiciary would stop them. Now, whether or not it would be a good idea for the US DoD to use Llama2, is a different question.
