what if doomsday and Grundy(JLU) is in the real world

your on a museum tour. your family is on a trip far away, and suddenly you hear screams outside. you look out and see doomsday and Solomon Grundy on a killing spree.

now, what would you do? what do you think the military would do?

I run away in my car, trying not to draw attention to me.

The military sends ground troop ( they get destroyed) followed by an air strike ( possibly effective) followed by gas attacks and possibly a missile or nuke

I'd slink away and make myself not look like any sort of threat (pretty easy to do since I'm only 105 lbs and 5'4)

The Military would send several groups of foot soldiers who'd get torn apart, then follow it with some Tanks, Air Strikes, and then if all else fails, Nukes.
