I've known plenty of people who do 400mg 2-3x/day for weeks/months.

Military?

Collegiate and professional athletes easily would do this. (I've personally done it, hell.)

Construction workers, manual laborers, etc.

True.

A lot of people I know that powerlift do 4 x 800mg for 5 days or so. I think the thinking is to give the injury a "blast" of ibuprofen to bring the swelling down fast, rather than a lower dose for a longer period.

Yes (and contractors, etc.)

I remember reading in a Tom Clancy book once that it's called "Light Fighter Candy".
