There are many police and second tier SF teams that train only with paper targets, sometimes steel reaction targets in the mix, or robotic range targets (basically the target silhouette moving on an electric rail system), or shooting at target mannequins...
We have always recommended that training should replicate real life.. at minimum mannequins holding SHOOT or NO SHOOT items should be used... regardless of range lighting conditions.
Night, and day plus distraction devices (for example shock wave simulators and strobes etc) are available in more advanced ranges in www.KASOTC.com
Actions of Team Members are even recorded on wall mounted camera in advanced firing ranges.
SF team members need realism-- not the first time realism expected when responding to a real life incident.
Whereas a lot of SF instructors teach "running the walls" upon room entry-- consider this-- in the real world desks, furniture and various obstacles line the walls... learn to improvise... run over, run around or even shoot through obstacles when in doubt.
