Mystery weapons allow for all sorts of deniability. With snipers and stuff there's always a pretty clear starting point for investigators to (attempt to) trace back to the source. That's much harder with this mystery weapon. It's possible that whoever is using has determined that keeping US/Cuba relations frosty is high enough priority to use their 'secret' weapon.
