This is a recurring quest that can be obtained from Denis at the UC Exchange in Cydonia. He'll send you to a generic location on a remote planet to acquire equipment from 'some bad guys' (i.e. one of the hostile factions). When you land at the indicated spot, the quest updates and tells you which items you are supposed to retrieve. In my case, it was five specific Crimson Fleet helmets. Sadly though, the chest the marker was pointing to contained only one of these helmets [also worth mentioning here is that this item is not handled by the game like other quest items, in that it doesn't get hidden in the trade menus and thus can be sold inadvertently. It can also be dropped and moved to any container.]. Nonetheless, when I grabbed it, the quest updated, telling me that I had acquired the items (when I obviously didn't !) and that I should return to Denis. Who subsequently told me thad I had only part of the items he wanted and that I should come back when I have all of them. The only way to complete the quest now is finding four more of these helmets by chance. Considering how other quests in Bethesda games are constructed, this is unlikely to have been intended.
