Example: "Raiders of the Lost Ark"

Which of the world's known governments (did or would do) today or historically is/was likely to be sending, or have sent, their forces out across the world looking for old stuff whether on land (like antartica) or underwater?

Such as govt forces looking for old stuff mythical or not across world.

As seen in "Raiders of the Lost Ark", for example.

What do historians have to share on this?
