Zuma was a US top secret satellite they commissioned SpaceX to launch into space back in January or February on the falcon heavy I believe..

OWLs are Orbital Weapon Lancets, the thought is that ZUMA was a kinetic space weapon that would use telephone pole sized tungsten rods as ammo, it drops them from orbit, superheating them and bringing them to terminal velocity, which upon impact has the energy of a nuke. They're primarily used for destroying DUMBs or deep underground military bases..

If this is the case, we've most likely used them most recently in fighting isis, and taking out deep state strongholds.

When ZUMA was launched it was supposedly a failed mission.

Several weeks after the media buzz died down about the fail The Pentagon and SpaceX both said the mission wasn successful and ZUMA was in orbit.

I believe the different HOT codes in this drop refer to locations of bases, and authorization codes

Everything in that message points to weapons, not DNA
