So this is what I have troubles wrapping my head around. It seems there are level III/IV icw plates on the market that have had excellent reviews in the past. However, they are not listed on the NIJ 06 approved list. What am I missing here? What is the status of plates like the AMI TAC3S, Velocity System P34, AT LESAPI. So are there plates flying under the radar because the NIJ standard is pigeon holing level III or level IV or because the companies don't submit the sample plates to be tested in both categories, or are the model numbers displayed by NIJ not the same as the model names provided for retail? I get the impression that level IV doesn't mean that it will stop the multi hit rounds of level III. However, there have been level III icw plates that can actually rate level IV and special threat plates that will allegedly protect against both that aren't rated NIJ 06 for either III or IV. Then some of these plates do throw in an NIJ rating using NIJ .04 rather than NIJ .06. It seems like every company would cater to the ICW crowd with the latest NIJ testing standard as agencies are looking into patrol officers having the throw on option. Just trying to get a handle on this, so sorry for my scattered thought process.
