Navy , especially subs has to contend with mega sharks quite regularly; it’ll only become more common with climate change too.
But what about giant octopuses?
yeah also pretty lethal, they can take out fighter jets.
Also mainly a Navy responsibility - those guys can’t catch a break.AFAIK mega-sharks are only known to attack civilian aircraft so far . . .
Well if Marines have aliens under control then who the heck are we putting Space Force up against?
The Goa’uld.
SG1 already took care of them
Humans from the distant future / past

You know those enemies really should stop wearing hats with big arrows on them, I feel like they would have a better chance that way.
Kaiju start with the Navy as they rise from the ocean, and then step on the army and breathe lightning on the air force. Their opposition is the national science foundation and the department of energy (who is also who generally wakes them up with some sort of nuclear accident).
