I’m thinking ‘Sword’ is a rebel faction within the marines founded by Garp that are against the way the Gorosei run tings.
Fact that Garp told Neptune to not be scared of humans and that marines are trying to solve the problem Indicates that some marines are working under the radar of the WG itself. Since ordinarily the marines don’t really give a shit. Or rather, don’t have any power to do anything about it.
Also the fact that Drake is communicating with Coby & that even Kizaru doesn’t know about sword further hints that this unit was created by Garp given Coby trained under Garp.
Lastly, if this sword unit is tied to Garp, chances are that Aokiji is currently under cover for sword as well under BB given he’s also connected to Garp & and like Coby & Drake, give off a feel of being righteous/uncorrupt marines.

And Drake contacted Coby that link back to Garp, so i guess connections are indeed there.
Also, During Rodger n Shiki flashback and after EL when Garp when to meet Luffy it was shown Aokiji was also close to Garp. Again meets the requirements. I can second this thoery.
