In times of danger, angels can throw them like weapons at their opponent. There's no worry of losing it, as the halo will return to the angel once it comes to a full stop. In times of boredom, they can also be thrown as frisbees in a sort of game. There are in fact contests held every year in the Order where the point is for an angel to throw its halo and the archer must attempt to fire through the hole in the halo (There's no fear of damaging the halo, it reforms on its own). The one who wins gets an angel companion to help carry their stuff, sight enemies, and alert the archers by - yet again - throwing their halos in the direction of their enemy as a signal.

They also make good light sources, able to release a light more powerful than a torch's and more consistent. But perhaps their most useful function regards their peculiar reaction to demonic energy. In short, due to this reaction there's no way for a mamono to fully hide their presence from an angel. This has saved countless soldiers from ambushes. Of course, when it comes to traitors their basic shape makes them good makeshift nooses as well.

And that's about all the BS I can pull out of my ass for this explanation.
