They aren't unmarked - their camouflage uniform clearly says "POLICE" on the front.

To be clear, do not shoot someone with POLICE written on their uniform, or even anyone you suspect might be a police officer, because you will spend the rest of your life in jail.

The pics I’ve seen show a small “police” patch in dark lettering over camo obscured by assault rifle straps and equipment. That’s not very clear in the dark when they don’t identify themselves and are putting a bag over your head

I would call that unmarked, as I’m not aware of any federal agency who identifies themselves as “police”.

They also have agency patches on — there's a lot of misinformation being spread about them being unidentified.
