Yeah if you see something labelling itself "MIL-SPEC", that's grade A snake oil bullshit.

That said military spec stuff is actually generally a good sign that something is of higher quality than random off the shelf garbage but only if you know there's a specific spec you want it to work with. And most of the time you aren't even necessarily looking for a MIL-STD (standard) but rather a MIL-PRF (performance rating/spec).

So like if something is "MIL-SPEC" run. But if you see say a spool of fiber that is "MIL-STD-1678 compliant" and more importantly "MIL-PRF-49291 compliant" and "MIL-PRF-85054 compliant", that's probably a really good sign that it'll do its job. The former PRF documenting perf requirements for the fiber itself and the latter PRF the cabling/sheath's corrosion and deterioration resistance.

It's the military so odds are it'll probably cost extra for that and it'll still kinda suck but it'll suck in exactly the way they promised.
