The Raven Shield Zone got a chance to ask active LAPD officer and Rainbow Six consultant Mike Grasso a few questions about the game. Here is a clip:

Is the new equipment in Raven Shield actual equipment in use today? (The heartbeat sensor goggles, and the thermal imaging scope)

All the equipment available to TR6 exists in some form. Wheter or not it is available on a weapon platform or stand-a-lone is a game decision.
