What is MaxWalkSpeed?

What is it? What is it measured in? Is it Unreal units per second? Or hour? Or minute? Or something else? (As used in the CharacterMovement component.)

I saw a thread that talked about how someone was hitting a max fall speed of 4000 UU’s, but that when running/walking they didn’t hit that limit.

I suspect it is Unreal units per second.
