But that is a steel plate. Ceramic is different.

Here is a video about the new 6.8x51mm Rifle round vs Level IV ceramic.
It has annoying background music but still. The 6.8 is a fast round particularly the high pressure steel based version and this armour can't stop two of the high pressure rounds if they hit in a similar area. 5.45 would take more rounds to get through it of course.
