Stand alone level IV trauma plates--steel or Ceramic?

[Chaplain Scott]

So, I am in the local Reserve Police Academy (as a regular entry level Deputy). I have been talking to some of the full-time Deputies here in rural south-central Montana, and when we get called to Domestics, they often will put on a plate carrier (and grab the AR as well). There are two or three deputies for 1,800 sq miles and back-up can be a LONG time coming. So, I am looking at Level IV stand-alone, multi-hit trauma plates.

I have been trying to do my research. I have been offered a really good deal on a carrier by First Spear. Most of the time, the plate carrier will be thrown on over a level IIIA vest, so I am thinking that steel would be acceptable in this instance, as the IIIA vest underneath should stop spalling. (correct assumption??)

However, there does exist the remote possibility of getting involved in a situation where the Level IIIA vest is not on, but the plate carrier is worn by itself. My guess is that in a situation like that, then the ceramic would be the better choice.

Cost is a factor, as we have to purchase all our own gear (including duty weapon, AR and practice ammo) and while I am pursuing the issue of Federal/State grants, $$ is still an issue.

Having said all that, I really wanted to ask the guys on this forum who are the true experts.

Thanks for the help & opinions!!
